bit 0

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

bit 7

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

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 – SPBRGH and SPBRG

0 = 8-bit Baud Rate Generator – SPBRG only (Compatible mode), SPBRGH value ignored

bit 2

Unimplemented: Read as ‘0’

bit 1

WUE: Wake-up Enable bit

Asynchronous mode:

1 = EUSART 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.
