bit 0
bit 7
Unimplemented: Read as â0â
bit 6
RCIDL: Receive Operation Idle Status bit
1 = Receiver is Idle
0 = Receiver is busy
bit 5
Unimplemented: Read as â0â
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 â SPBRGH and SPBRG
0 = 8-bit Baud Rate Generator â SPBRG only (Compatible mode), SPBRGH value ignored
bit 2
Unimplemented: Read as â0â
bit 1
WUE: Wake-up Enable bit
Asynchronous mode:
1 = EUSART will continue to sample the RX pin â 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 â requires reception of a Sync byte
(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
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared x = Bit is unknown
