Multiprocessor Communication Enable.
0: RI0 will be activated if stop bit(s) are 1.
1: RI0 will be activated if stop bit(s) and extra bit are 1. Extra bit must be enabled using
XBE0.
00: Odd Parity
01: Even Parity
10: Mark Parity
11: Space Parity.
Parity Enable.
This bit enables hardware parity generation and checking. The parity type is selected
by bits S0PT[1:0] when parity is enabled.
0: Hardware parity is disabled.
1: Hardware parity is enabled.
00: 5-bit data
01: 6-bit data
10: 7-bit data
11: 8-bit data
Extra Bit Enable.
When enabled, the value of TBX0 will be appended to the data field
0: Extra Bit is disabled.
1: Extra Bit is enabled.
Stop Bit Length.
0: Short—stop bit is active for one bit time
1: Long—stop bit is active for two bit times (data length = 6, 7, or 8 bits), or 1.5 bit times
(data length = 5 bits).
