I try use The Pretended Networking of CAN on S32K,in Freeze mode ,I set CAN_MCR_PNET_EN =1,but CAN_MCR_LPMACK_SHIFT still is 0.why? I need your help,
Thanks very much!
The LPMACK is set once Module disable or in Stop mode is entered. See chapter 49.2.3 Modes of operation” and 126.96.36.199 “Pretended Networking Mode” of the device Reference Manual.
The PNET_EN just enable Pretended Networking mode, but do not cause low power mode entry.
