Bus off interrupt. The BOFFINT bit is used to request an interrupt when the TouCAN enters
the bus off state.
0 No bus off interrupt requested
1 When the TouCAN state changes to bus off, this bit is set, and if the BOFFMSK bit in
Error Interrupt. The ERRINT bit is used to request an interrupt when the TouCAN detects a
transmit or receive error.
0 No error interrupt request
1 If an event which causes one of the error bits in the error and status register to be set
To clear this bit, first read it as a one, then write as a zero. Writing a one has no effect.
Wake interrupt. The WAKEINT bit indicates that bus activity has been detected while the
TouCAN module is in low-power stop mode.
