I am trying to enable/disable Vaux, present on KITFS6522LAEEVM, through my MPC5643L dspi module. The intention is to blink the green LED that's connected to the Vaux. I want to be able to blink this to show it's possible to control Vaux through software from the microcontroller. But I am unable to find information on how to set/reset this register.
And as a larger picture, I am unable to find a document that shows WHAT VALUE to write into registers of the SBC so do tasks I need. For example, I don't know what value to write to CAN registers to enable it, transmit something, disable it, etc.
Any help would be appreciated. Thank you.
