ABDOVF: Auto-Baud Acquisition Rollover Status bit
1 = A BRG rollover has occurred during Auto-Baud Rate Detect mode (must be cleared in software)
0 = No BRG rollover has occurred
RCIDL: Receive Operation Idle Status bit
1 = Receive operation is Idle
0 = Receive operation is active
Unimplemented: Read as ‘0’
SCKP: Synchronous Clock Polarity Select bit
Asynchronous mode:
Unused in this mode.
Synchronous mode:
1 = Idle state for clock (CK1) is a high level
0 = Idle state for clock (CK1) is a low level
BRG16: 16-Bit Baud Rate Register Enable bit
1 = 16-bit Baud Rate Generator – SPBRGH1 and SPBRG1
0 = 8-bit Baud Rate Generator – SPBRG1 only (Compatible mode), SPBRGH1 value ignored
Unimplemented: Read as ‘0’
WUE: Wake-up Enable bit
Asynchronous mode:
1 = EUSART will continue to sample the RX1 pin – interrupt generated on falling edge; bit cleared in
0 = RX1 pin not monitored or rising edge detected
Synchronous mode:
Unused in this mode.
ABDEN: Auto-Baud Detect Enable bit
Asynchronous mode:
1 = Enable baud rate measurement on the next character. Requires reception of a Sync field (55h);
0 = Baud rate measurement disabled or completed
Synchronous mode:
Unused in this mode.
RCIDL
