RWRNIF — Receiver Warning Interrupt Flag
TWRNIF — Transmitter Warning Interrupt Flag
RERRIF — Receiver Error Passive Interrupt Flag
TERRIF — Transmitter Error Passive Interrupt Flag
1. Condition to set the flag: RWRNIF = (96 ≤ REC ≤ 127) & RERRIF & TERRIF & BOFFIF
2. Condition to set the flag: TWRNIF = (96 ≤ TEC ≤ 127) & RERRIF & TERRIF & BOFFIF
3. Condition to set the flag: RERRIF = (128 ≤ REC ≤ 255) & BOFFIF
4. Condition to set the flag: TERRIF = (128 ≤ TEC ≤ 255) & BOFFIF
This flag is set when the msCAN12 goes into warning status due to
the Receive Error counter (REC) exceeding 96 and neither one of the
Error interrupt flags or the Bus-Off interrupt flag is set
masked, an Error interrupt is pending while this flag is set.
This bit will be set when the msCAN12 goes into warning status due
to the Transmit Error counter (TEC) exceeding 96 and neither one of
the Error interrupt flags or the Bus-Off interrupt flag is set
masked, an Error interrupt is pending while this flag is set.
This flag is set when the msCAN12 goes into error passive status due
to the Receive Error counter (REC) exceeding 127 and the Bus-Off
interrupt flag is not set
while this flag is set.
This flag is set when the msCAN12 goes into error passive status due
to the Transmit Error counter (TEC) exceeding 127 and the Bus-Off
interrupt flag is not set
while this flag is set.
0 = No receiver warning status has been reached.
1 = msCAN12 went into receiver warning status.
0 = No transmitter warning status has been reached.
1 = msCAN12 went into transmitter warning status.
0 = No receiver error passive status has been reached.
1 = msCAN12 went into receiver error passive status.
0 = No transmitter error passive status has been reached.
1 = msCAN12 went into transmitter error passive status.
