7.6.5
The transmit error counter has exceeded the error-
passive limit of 127 and the device has gone to error-
passive state.
7.6.6
The transmit error counter has exceeded 255 and the
device has gone to bus-off state.
7.7
Interrupts are directly associated with one or more sta-
tus flags in the CANINTF register. Interrupts are pend-
ing as long as one of the flags is set. Once an interrupt
flag is set by the device, the flag can not be reset by the
MCU until the interrupt condition is removed.
