Hi,
I need to change my S32K144 board into a device that can be activated over CAN. It means I need to swap the board to permanently powered but to make use of low power modes as the boardwill be kept active with a low capacity starter lead acid battery (~1.6Ah).
Firstly, what mode would I need to set as my sleep mode to still allow CAN wake up functionality? Looking at the RM it seems like VLPS still allows CAN functionality?
Secondly, how would I implement this in my model. I ideally only want a specific frame ID to make the device from VLPS when received on the CAN bus.
This is what I have being called when I want the device to go to sleep. It sets the CAN transciever standby pin to high before callback (Puts transceiver into receive only low power mode - TJA1057) and then resets it to low for normal mode on callback exit.
How do I then wake this back up with a CAN frame?
Thanks in advance for the help! @mariuslucianand I am not sure if this is something you would know already and therefore hopefully straight forward
