We use MPC5738G IO PH13 and PH15 as FCCU IO.
MPC5748G PH15 (symbol MCU1_FCCU_F0) with external pull down.
MPC5748G PH13 (symbol MCU1_FCCU_F1) with external pull high.
The problem is :
When MPC5748G executes functional reset with register programming on MC_ME_MCTL, there's small period of time that pin status of PH13 and PH15 of MPC5748G resets to default. This is treated as an error of bi-stable protocol. But there's no real error happen in MCU side.
Could you please check if there's any problem with this design? Any possible solution?
