Unimplemented: Read as ‘0’
Unimplemented: Read as ‘0’
B1BFS: RX1BF Pin State bit (Digital Output mode only)
- Reads as ‘0’ when RX1BF is configured as interrupt pin
B0BFS: RX0BF Pin State bit (Digital Output mode only)
- Reads as ‘0’ when RX0BF is configured as interrupt pin
B1BFE: RX1BF Pin Function Enable bit
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 bit
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 bit
1 = Pin is used as interrupt when valid message loaded into RXB1
0 = Digital Output mode
B0BFM: RX0BF Pin Operation Mode bit
1 = Pin is used as interrupt when valid message loaded into RXB0
0 = Digital Output mode
Legend:
R = Readable bit
-n = Value at POR
SID: Standard Identifier bits <10:3>
These bits contain the eight most significant bits of the Standard Identifier for the received
message
