ABDOVF RCIDL
— SCKP BRG16 — WUE ABDEN
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
ABDOVF: Auto-Baud Detect Overflow bit
Asynchronous mode
:
1 = Auto-baud timer overflowed
0 = Auto-baud timer did not overflow
Synchronous mode
:
Don’t care
bit 6
RCIDL: Receive Idle Flag bit
Asynchronous mode
:
1 = Receiver is Idle
0 = Start bit has been received and the receiver is receiving
Synchronous mode
:
Don’t care
bit 5
Unimplemented: Read as ‘0’
bit 4
SCKP: Synchronous Clock Polarity Select bit
Asynchronous mode
:
1 = Transmit inverted data to the TX/CK pin
0 = Transmit non-inverted data to the TX/CK pin
Synchronous mode
:
1 = Data is clocked on rising edge of the clock
0 = Data is clocked on falling edge of the clock
bit 3
BRG16: 16-bit Baud Rate Generator bit
1 = 16-bit Baud Rate Generator is used
0 = 8-bit Baud Rate Generator is used
bit 2
Unimplemented: Read as ‘0’
bit 1
WUE: Wake-up Enable bit
Asynchronous mode
:
1 = Receiver is waiting for a falling edge. No character will be received, byte RCIF will be set. WUE
will automatically clear after RCIF is set.
0 = Receiver is operating normally
Synchronous mode
:
Don’t care
bit 0
ABDEN: Auto-Baud Detect Enable bit
Asynchronous mode
:
1 = Auto-Baud Detect mode is enabled (clears when auto-baud is complete)
0 = Auto-Baud Detect mode is disabled
Synchronous mode
:
Don’t care
