bit 7

bit 0

bit 7

SPEN: Serial Port Enable bit

1 = Serial port enabled (configures RC7/RX/DT and RC6/TX/CK pins as serial port pins)

0 = Serial port disabled

bit 6

RX9: 9-bit Receive Enable bit

1 = Selects 9-bit reception

0 = Selects 8-bit reception

bit 5

SREN: Single Receive Enable bit

Asynchronous mode:

Don’t care

Synchronous mode - Master:

1 = Enables single receive

0 = Disables single receive

This bit is cleared after reception is complete.

Synchronous mode - Slave:

Don’t care

bit 4

CREN: Continuous Receive Enable bit

Asynchronous mode:

1 = Enables continuous receive

0 = Disables continuous receive

Synchronous mode:

1 = Enables continuous receive until enable bit CREN is cleared (CREN overrides SREN)

0 = Disables continuous receive

bit 3

Unimplemented: Read as '0'

bit 2

FERR: Framing Error bit

1 = Framing error (can be updated by reading RCREG register and receive next valid byte)

0 = No framing error

bit 1

OERR: Overrun Error bit

1 = Overrun error (can be cleared by clearing bit CREN)

0 = No overrun error

bit 0

RX9D: 9th bit of Received Data. (Can be parity bit. Calculated by firmware.)

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
