Hi All,
I am using MC9S12ZVLA128 micro for my application. I am using external 10MhZ clock crystal.
And I have used the OMRE(Oscillator monitor Reset Enable) feature of the MCU.
As a part of my application feature, I have to write one pattern to EEPROM after getting restart from PLL lock reset based on the status of the reset flag register.
Here I want to test my code by reproducing the scenario that causes the PLL lock reset. I am not sure how to reproduce the PLL lock reset.
Can you help me on this with any test code or other steps to test my application software.
Regards,
Vyshakh J
Hi,
Unfortunately, there is no way for the user to trigger the PLL clock monitor reset (PMRF).
It is a safety feature and only for the case that the PLL is really damaged.
