CREN ADDEN  
FERR  
OERR  
R = Readable bit  
W = Writable bit  
U = Unimplemented bit,  
read as ‘0’  
- n = Value at POR reset  
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  
Unused in this mode  
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:  
ADDEN: Address Detect Enable bit  
Asynchronous mode 9-bit (RX9 = 1)  
1= Enables address detection, enable interrupt and load of the receive burffer when RSR<8> is set  
0= Disables address detection, all bytes are received, and ninth bit can be used as parity bit  
bit 2:  
bit 1:  
bit 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)
