bit 7
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
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
RX9
: 9-bit Receive Enable bit
1
= Selects 9-bit reception
0
= Selects 8-bit reception
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
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
Unimplemented:
Read as ‘
0
FERR
: Framing Error bit
1
= Framing error (can be updated by reading RCREG register and receive next valid byte)
0
= No framing error
OERR
: Overrun Error bit
1
= Overrun error (can be cleared by clearing bit CREN)
0
= No overrun error
RX9D:
9th bit of Received Data
Can be parity bit (parity to be calculated by firmware)
bit 6
bit 5
bit 4
bit 3
bit 2
bit 1
bit 0
