bit 7  
bit 6  
bit 5  
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:  
Dont care  
Synchronous mode - Master:  
1= Enables single receive  
0= Disables single receive  
This bit is cleared after reception is complete.  
Synchronous mode - Slave:  
Dont 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  
bit 2  
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  
bit 1  
bit 0  
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. Calculated by firmware.)  
Legend:  
R = Readable bit  
-n = Value at POR  
W = Writable bit  
U = Unimplemented bit, read as 0’  
0= Bit is cleared x = Bit is unknown  
1= Bit is set
