27.15.6.1 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.
27.15.6.2 Receiver Warning
The receive error counter has reached the MCU
warning limit of 96.
27.15.6.3 Transmitter Warning
The transmit error counter has reached the MCU
warning limit of 96.
27.15.6.4 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.
27.15.6.5 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.
27.15.6.6 Bus-Off
The transmit error counter has exceeded 255 and the
device has gone to bus-off state.
