HCS08 detecting LVD reset even though LVD is not enabled

prasad1 — Mon, 15 Jan 2018 07:54:43 GMT

Hi,

I am currently working on MC9S08SG8 microcontroller from HCS08 family. I have disabled Low voltage detection logic with SPMSC1 = 0; and SPMSC2 = 0. But after doing power on and off sometimes I see only LVD bit in SRS register is set(POR bit is not set) . But S08 microcontroller did not go through a reset. I am not able to understand this.Can anyone please help me to understand this behaviour?

Thanks,

Prasad
