LCR[3]: TX and RX Parity Select

Parity or no parity can be selected via this bit. The parity bit is a simple way used in communications for data

integrity check. See Table 5 for parity selection summary below.

• Logic 0 = No parity.

• Logic 1 = A parity bit is generated during the transmission while the receiver checks for parity error of the

data character received.

LCR[4]: TX and RX Parity Select

If the parity bit is enabled with LCR bit-3 set to a logic 1, LCR BIT-4 selects the even or odd parity format.

• Logic 0 = ODD Parity is generated by forcing an odd number of logic 1’s in the transmitted character. The

receiver must be programmed to check the same format (default).

• Logic 1 = EVEN Parity is generated by forcing an even number of logic 1’s in the transmitted character. The

receiver must be programmed to check the same format.
