SPEN
SPEN: Serial Port Enable bit
1 = Serial port enabled (configures RX1/DT1 and TX1/CK1 pins as serial port pins)
0 = Serial port disabled (held in Reset)
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 receiver
0 = Disables receiver
Synchronous mode:
1 = Enables continuous receive until enable bit, CREN, is cleared (CREN overrides SREN)
0 = Disables continuous receive
ADDEN: Address Detect Enable bit
Asynchronous mode 9-bit (RX9 = 1):
1 = Enables address detection, enables interrupt and loads the receive buffer when RSR<8> is set
0 = Disables address detection, all bytes are received and the ninth bit can be used as a parity bit
Asynchronous mode 9-bit (RX9 = 0):
Don’t care.
FERR: Framing Error bit
1 = Framing error (can be updated by reading RCREG1 register and receiving 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
This can be address/data bit or a parity bit and must be calculated by user firmware.
