[9S08SH] How to have a robust power on reset (POR)?

Hi all,


I use 9S08SH4 (TSSOP16) at 3.3 V but it does not start after a power on following immediately a power off. In this case, I just have to touch any component on my PCB so that it starts. If I wait for a few seconds before the power on it starts normally. I use two regulations of tension, linear regulator and buck converter but this issue appears in both cases.


An idea please?
