bit 0

bit 7

Unimplemented: Read as '0'

bit 6

Unimplemented: Read as '0'

bit 5

B1BFS: RX1BF Pin State (digital output mode only)

- Reads as ‘0’ when RX1BF is configured as interrupt pin

bit 4

B0BFS: RX0BF Pin State (digital output mode only)

- Reads as ‘0’ when RX0BF is configured as interrupt pin

bit 3

B1BFE: RX1BF Pin Function Enable

1 = Pin function enabled, operation mode determined by B1BFM bit

0 = Pin function disabled, pin goes to high impedance state

bit 2

B0BFE: RX0BF Pin Function Enable

1 = Pin function enabled, operation mode determined by B0BFM bit

0 = Pin Function disabled, pin goes to high impedance state

bit 1

B1BFM: RX1BF Pin Operation Mode

1 = Pin is used as interrupt when valid message loaded into RXB1

0 = Digital output mode

bit 0

B0BFM: RX0BF Pin Operation Mode

1 = Pin is used as interrupt when valid message loaded into RXB0

0 = Digital output mode

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
