23.15.5
When the PIC18F2585/2680/4585/4680 devices are in
Sleep mode and the bus activity wake-up interrupt is
enabled, an interrupt will be generated and the WAKIF
bit will be set when activity is detected on the CAN bus.
This interrupt causes the PIC18F2585/2680/4585/
4680 devices to exit Sleep mode. The interrupt is reset
by the MCU, clearing the WAKIF bit.
23.15.6
When the error interrupt is enabled, an interrupt is
generated if an overflow condition occurs or if the error
state of the transmitter or receiver has changed. The
error flags in COMSTAT will indicate one of the
following conditions.
23.15.6.1
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.
23.15.6.2
The receive error counter has reached the MCU
warning limit of 96.

Preliminary
23.15.6.3
The transmit error counter has reached the MCU
warning limit of 96.
23.15.6.4
The receive error counter has exceeded the error-
passive limit of 127 and the device has gone to
error-passive state.
23.15.6.5
The transmit error counter has exceeded the error-
passive limit of 127 and the device has gone to
error-passive state.
23.15.6.6
The transmit error counter has exceeded 255 and the
device has gone to bus-off state.
23.15.6.7
Interrupts are directly associated with one or more
status flags in the PIR register. Interrupts are pending
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
microcontroller until the interrupt condition is removed.
