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

Mode 0:
Unimplemented: Read as ‘0’
ICODE<3:1>: 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 ICODE<3:1> to WIN<3:0> (Mode 0) or EICODE<4:0> to
EWIN<4:0> (Mode 1 and 2), it is possible to select the correct buffer to map into the Access Bank area.
See Example 24-2 for a code example. To simplify the description, the following table lists all five bits.
