B2RTS: TX2RTS Pin State bit
- Reads state of TX2RTS pin when in Digital Input mode
- Reads as ‘0’ when pin is in ‘Request-to-Send’ mode
B1RTS: TX1RTX Pin State bit
- Reads state of TX1RTS pin when in Digital Input mode
- Reads as ‘0’ when pin is in ‘Request-to-Send’ mode
B0RTS: TX0RTS Pin State bit
- Reads state of TX0RTS pin when in Digital Input mode
- Reads as ‘0’ when pin is in ‘Request-to-Send’ mode
B2RTSM: TX2RTS Pin mode bit
1 = Pin is used to request message transmission of TXB2 buffer (on falling edge)
0 = Digital input
B1RTSM: TX1RTS Pin mode bit
1 = Pin is used to request message transmission of TXB1 buffer (on falling edge)
0 = Digital input
B0RTSM: TX0RTS Pin mode bit
1 = Pin is used to request message transmission of TXB0 buffer (on falling edge)
0 = Digital input
