ABDOVF
One bit has been added to the BAUDCON register
and one bit has been renamed. The added bit is
RXDTP and is in the location, BAUDCON<5>. The
renamed bit is the TXCKP bit (BAUDCON<4>),
which had been named SCKP.
The
(BAUDCON<5>) bits enable the Synchronous
mode TX and RX signals to be inverted (polarity
reversed).
Synchronous mode DT signal.

TXCKP
Synchronous Receiver
Transmitter (EUSART)
ABDOVF: Auto-Baud Acquisition Rollover Status bit
1 = A BRG rollover has occurred during Auto-Baud Rate Detect mode
0 = No BRG rollover has occurred
RCIDL: Receive Operation Idle Status bit
1 = Receive operation is Idle
0 = Receive operation is Active
RXDTP: Receive Data Polarity Select bit (Asynchronous mode only)
Asynchronous mode:
1 = Receive data (RX) is inverted. Idle state is a low level.
0 = No inversion of receive data (RX). Idle state is a high level.
TXCKP: Transmit/Clock Polarity Select bit
Asynchronous mode:
1 = Transmit data (TX) is inverted. Idle state is a low level.
0 = No inversion of transmit data (TX). Idle state is a high level.
Synchronous mode:
1 = Idle state for clock (CK) is a high level
0 = Idle state for clock (CK) is a low level
BRG16: 16-bit Baud Rate Register Enable bit
1 = 16-bit Baud Rate Generator – SPBRGH and SPBRG
0 = 8-bit Baud Rate Generator – SPBRG only (Compatible mode); SPBRGH value ignored
Unimplemented: Read as ‘0’
WUE: Wake-up Enable bit
Asynchronous mode:
1 = EUSART will continue to sample the RX pin with the interrupt generated on the falling edge; bit
0 = RX pin is not monitored or rising edge detected
Synchronous mode:
Unused in this mode.
