bit 0
bit 7
Unimplemented: Read as ‘0’
bit 6
RCIDL: Receive Operation IDLE Status bit
1 = Receive operation is IDLE
0 = Receive operation is active
bit 5
Unimplemented: Read as ‘0’
bit 4
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
bit 3
BRG16: 16-bit Baud Rate Register Enable bit
1 = 16-bit baud rate generator - SPBRGHx and SPBRGx
0 = 8-bit baud rate generator - SPBRGx only (Compatible mode), SPBRGHx value ignored
bit 2
Unimplemented: Read as ‘0’
bit 1
WUE: Wake-up Enable bit
Asynchronous mode:
1 = USART will continue to sample the RX pin - interrupt generated on falling edge; bit cleared
in hardware on following rising edge
0 = RX pin not monitored or rising edge detected
Synchronous mode:
Unused in this mode.
bit 0
ABDEN: Auto Baud Detect Enable bit
Asynchronous mode:
1 = Enable baud rate measurement on the next character - requires reception of a Sync field
(55h); cleared in hardware upon completion
0 = Baud rate measurement disabled or completed
Synchronous mode:
Unused in this mode.
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
