BAUDCTL: BAUD RATE CONTROL REGISTER
bit 7
Unimplemented: Read as ‘0’
RCIDL: Receive Operation Idle Status bit
1 = Receiver is Idle
0 = Receive in progress
Unimplemented: Read as ‘0’
SCKP: Synchronous Clock Polarity Select bit
Asynchronous mode:
Unused in this mode
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 = USART will continue to sample the RX pin – interrupt generated on falling edge; bit cleared
0 = RX 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
0 = Baud rate measurement disabled or completed
Synchronous mode:
Unused in this mode
