14.3.3 Interrupt Status Registers
The flags in the interrupt status registers identify maskable interrupt sources.
interrupt sources and the interrupt status register flags that they set. The interrupt status registers can be
useful for debugging.

•
Bus Off bit (BOFFIF) — BOFFIF is set when the transmit error counter has exceeded 255 and
MSCAN08 has gone to bus off state. The bus off interrupt enable bit, BOFFIE, enables BOFFIF to
generate MSCAN08 error CPU interrupt requests. BOFFIF is in MSCAN08 receiver flag register.
BOFFIE is in MSCAN08 receiver interrupt enable register.
