— — B1BFS B0BFS B1BFE B0BFE B1BFM B0BFM
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-6 Unimplemented: Read as ‘0’
bit 5 B1BFS:
RX1BF Pin State bit (Digital Output mode only)
- Reads as ‘0’ when RX1BF is configured as an interrupt pin
bit 4 B0BFS: RX0BF Pin State bit (Digital Output mode only)
- Reads as ‘0’ when RX0BF is configured as an interrupt pin
bit 3 B1BFE:
RX1BF Pin Function Enable bit
1 = Pin function is enabled, operation mode is determined by the B1BFM bit
0 = Pin function is disabled, pin goes to a high-impedance state
bit 2 B0BFE:
RX0BF Pin Function Enable bit
1 = Pin function is enabled, operation mode is determined by the B0BFM bit
0 = Pin function is disabled, pin goes to a high-impedance state
bit 1 B1BFM:
RX1BF Pin Operation mode bit
1 = Pin is used as an interrupt when a valid message is loaded into RXB1
0 = Digital Output mode
bit 0 B0BFM:
RX0BF Pin Operation mode bit
1 = Pin is used as an interrupt when a valid message is loaded into RXB0
0 = Digital Output mode
