-- Usage of Nexys 4 Switches, Buttons, LEDs
--
-- SWI(15:5): no function (only connected to sn_humanio_rbus)
-- (5): select DSP(7:4) display
-- 0 abclkdiv & abclkdiv_f
-- 1 PC
-- (4): select DSP(3:0) display
-- 0 DISPREG
-- 1 DR emulation
-- (3): select LED display
-- 0 overall status

-- (1): 1 enable XON
-- (0): unused-reserved (serial port select)
--
-- LEDs if SWI(3) = 1

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

-- Filename: basic_sfifo_fg.vhd
--
-- Description:
-- This HDL file implements a basic synchronous (single clock) fifo using the
-- FIFO Generator tool. It is intended to offer a simple interface to the user
-- with the complexity of the FIFO Generator interface hidden from the user.
--
-- Note that in normal op mode (not First Word Fall Through FWFT) the data count
-- output goes to zero when the FIFO goes full. This the way FIFO Generator works.

--
-- with TTL serial interface following the RS232 timing format,
-- when there is no data, the line should idle as a '1'
-- The start of a byte transmission always starts with a start bit '0'
-- which last 1 bit period in length ( 1/baudrate )
--
-- The rx_start_detector detect's when a falling_edge occurs on rx_uart.
-- if the rx_sample_timing_gen is in state 0, it will start generating
-- the sampling clock enables when rx_start_det = '1'.
--
-- The rx_byte_builder receives the sample_ce sigals from the sample
-- timing generator and shifts in the value of the rx_uart line on
-- each clock enable building a byte.
--
-- Note that the rx_sample_timing_gen does not produces a sample_ce
-- for the start or stop bits.
--
-- In RS232 TTL levels, > 2.5v is a '0' and < 2.5v is a '1'.
-- serial data is transmited as LSB first.
--
-- ** Top Level interaction Note:
--
-- There is no real output buffering going on in this code.
-- if we finish receiving a incomming byte and the last working byte
-- has not been read yet, we will overwrite it transparently.
-- ( On overflow, ew drop the oldest data )
--
-- This shouldn't really be a big issue since the update rate is
-- very slow (500+ clock cycles) for each byte. It is assmed
-- that upper level components will read the byte as soon as
-- it is available and perform there own buffering if needed.

-- The tx_timing_generate just takes the i_clk signal and divides down

-- This will cause the state machine to load the tx_shift_register
-- with the new byte and to shift it own with a start bit prepended.
