Table 22. Write Register 4 Rx and Tx Control
Parity (D0)
If this bit is set, an additional bit position is added to transmitted data and is
expected in receive data. This added bit position is in addition to those bits
specified in the bits/character control. In the Receive mode, the parity bit
received is transferred to the CPU as part of the character, unless eight bits/
character is selected.
Parity Even/Odd (D1)
If parity is specified, this bit determines whether the bit is sent and checked
as even or odd (1 = even).
Stop Bits 0 and 1 (D2 and D3)
These bits determine the number of stop bits added to each asynchronous
character sent. The receiver always checks for one stop bit. A special mode
(00) designates that a synchronous mode is to be selected.
