bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
bit 7
SPEN:
Serial Port Enable bit
1
= Serial port enabled (configures RX/DT and TX/CK pins as serial port pins)
0
= Serial port disabled (held in Reset)
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 receiver
0
= Disables receiver
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 the receive buffer when RSR<8> is set
0
= Disables address detection, all bytes are received and ninth bit can be used as parity bit
Asynchronous mode 8-bit (RX9 =
0
):
Don’t care
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:
Ninth bit of Received Data
This can be address/data bit or a parity bit and must be calculated by user firmware.
