RS232

This code reception part is not working. There is no checking for stop bits.
Can you share working of uart reception code

rx_code

The code for the receiver isn't working.
A word can be restarted in the middle of a word since the rx_rcv_init can be set in the middle of a word as soon as Rx input goes low.
The start bit can be interpreted as a data bit since the clock can be generated twice.
(I might submit working code on request after I got it working).

Receiver code isn't working

Implementation of 8250 registers and signals compatibility to block.

8250 Compatibility

Implement Wishbone interface to use RS232/UART interface as generic peripheral.

Wishbone implementation

Implement inter frame gap to avoid sync fail.

Inter frame gap

Parity bit

Need to change the implementation of BAUD RATE generation to be dynamic.
It can be implemented as a table of value to the most used BAUD RATEs(9600,115200,etc) avoiding consume of area.

Change BAUD_RATE from GENERIC to IN PORT

Change tx_req to tx_send;
Change rx_ready to rx_dv;
