hi,

We are facing an issue in sleep and wakeup functionality for S12ZVMC128.

We are setting the following registers before enetring into sleep mode:

CANRIER|=0x80;
CANCTL0|=0x06;

We have observed that the MSCAN enetrs into sleep mode by monitoring the SLPAK bit in the CANCTL1 register, Whereas, the controller is still in active state as the current consumption does not reduce.

Please provide the Port Pin settings to enter into controller sleep state and let me know the procedure that is followed.
