Note 1:
2:
To achieve maximum power saving and/or able to wake-up on CAN bus activity, switch CAN module in
Disable mode before putting device to Sleep.
If buffer is configured as receiver, EICODE bits will contain ‘10000’ upon interrupt.

ICODE3:ICODE1: Interrupt Code bits
When an interrupt occurs, a prioritized coded interrupt value will be present in these bits. This code
indicates the source of the interrupt. By copying ICODE3:ICODE1 to WIN2:WIN0 (Mode 0) or
EICODE4:EICODE0 to EWIN4:EWIN0 (Mode 1 and 2), it is possible to select the correct buffer to map into
the Access Bank area. See Example 23-2 for a code example. To simplify the description, the following
table lists all five bits.
