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
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
bit 4
Unimplemented: Read as ‘0’
SCKP: Synchronous Clock Polarity Select bit
Asynchronous mode:
1= Transmit pin TX
0= Transmit pin TX
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
bit 1
Unimplemented: Read as ‘0’
WUE: Wake-up Enable bit
1= Next falling RX/DT edge will generate interrupt (automatically cleared on next rising edge
after falling edge)
0= RX/DT edges do not generate interrupts
bit 0
ABDEN: Auto Baud Detect Enable bit
Asynchronous mode:
1= Auto Baud mode is enabled (clears when auto baud is complete)
0= Auto Baud mode is disabled
Synchronous mode:
Don’t care
Legend:
R = Readable bit
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
- n = Value at POR
