Unimplemented: Reads as ‘0’
Unimplemented: Reads as ‘0’
B1BFS: RX1BF Pin State (digital output mode only)
Reads as 0 when RX1BF is configured as interrupt pin
B0BFS: RX0BF Pin State (digital output mode only)
Reads as 0 when RX0BF is configured as interrupt pin
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
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
B1BFM: RX1BF Pin Operation Mode
1 = Pin is used as interrupt when valid message loaded into RXB1
0 = Digital output mode
B0BFM: RX0BF Pin Operation Mode
1 = Pin is used as interrupt when valid message loaded into RXB0
0 = Digital output mode
These bits contain the eight most significant bits of the Standard Identifier for the received message
