24.15.6.1 Receiver Overflow

An overflow condition occurs when the MAB has

assembled a valid received message (the message

meets the criteria of the acceptance filters) and the

receive buffer associated with the filter is not available

for loading of a new message. The associated

RXBnOVFL bit in the COMSTAT register will be set to

indicate the overflow condition. This bit must be cleared

by the MCU.

24.15.6.2 Receiver Warning

The receive error counter has reached the MCU

warning limit of 96.

24.15.6.3 Transmitter Warning

The transmit error counter has reached the MCU

warning limit of 96.

24.15.6.4 Receiver Bus Passive

This will occur when the device has gone to the error-

passive state because the receive error counter is

greater or equal to 128.

24.15.6.5 Transmitter Bus Passive

This will occur when the device has gone to the error-

passive state because the transmit error counter is

greater or equal to 128.

24.15.6.6 Bus-Off

The transmit error counter has exceeded 255 and the

device has gone to bus-off state.
