Bit 7 – ABDOVF Auto-Baud Detect Overflow bit

ValueNameDescription
1 SYNC = 0

Auto-baud timer overflowed
0 SYNC = 0

Auto-baud timer did not overflow
X SYNC = 1

Don’t care

Bit 6 – RCIDL Receive Idle Flag bit

ValueNameDescription
1 SYNC = 0

Receiver is Idle
0 SYNC = 0

Start bit has been received and the receiver is receiving
X SYNC = 1

Don’t care

Bit 4 – SCKP Synchronous Clock Polarity Select bit

ValueNameDescription
1 SYNC = 0

Idle state for transmit (TX) is a low level (transmit data inverted)
0 SYNC = 0

Idle state for transmit (TX) is a high level (transmit data is noninverted)
1 SYNC = 1

Data is clocked on rising edge of the clock
0 SYNC = 1

Data is clocked on falling edge of the clock

Bit 3 – BRG16 16-bit Baud Rate Generator Select bit

ValueDescription
1

16-bit Baud Rate Generator is used
0

8-bit Baud Rate Generator is used

Bit 1 – WUE Wake-Up Enable bit

ValueNameDescription
1 SYNC = 0

Receiver is waiting for a falling edge. Upon falling edge, no character will be received and the RCxIF flag will be set. WUE will automatically clear after RCxIF is set.
0 SYNC = 0

Receiver is operating normally
X SYNC = 1

Don’t care

Bit 0 – ABDEN Auto-Baud Detect Enable bit

ValueNameDescription
1 SYNC = 0

Auto-Baud Detect mode is enabled (clears when auto-baud is complete)
0 SYNC = 0

Auto-Baud Detect is complete or mode is disabled
X SYNC = 1

Don’t care
