The SPC58 MCU has no responsing for the PORST reset

[YYM]

The mcu of SPC58 does not response the PORST reset. I knew one case that the mcu actives the reset escalation, but  MC_RGM.FRET.R and MC_RGM.DRET.R  have been set 0; I want know other possiable reason ?

This problem confused me long time.  

Thank you for give me some clue about this.

Hello ,

According to the RM 

Peripheral Reset Register 0 (RGM_PRST0)

This register provides individual resets for various peripherals. It can be accessed in
read/write in either supervisor mode or test mode. It can be accessed in read only in user
mode.

Reset escalation may happen after a lot of watchdog timer issues 

Have you got the hand on the MCU ?
