Hi Team,
There's an issue from the customer need your help:
When the voltage crosses the POR threshold, the internal brownout-reset (BOR) circuit takes
control and holds the device in reset until the voltage crosses the BOR threshold
The BOR is
enabled by default. To disable the BOR, set the BORLVMONDIS bit in the VMONCTL register.
That is the description of BOR and POR above.
There is a issue:
The BOR of the 280049 was measured at 2.88V and now I want to test POR
1. Disable the BOR
2. VDDIO voltage from 2.0V to 3.3V'
3. Observe XRSn status and chip status
By following those steps to test POR and found the chip work unproperly until voltage up to 2.88V, but I closed BOR function already, how do I test POR=2.3V?
tips: Disable Bor, we see that the chip is reset when VDDIO is powered down to 2.31V, is this a POR or PDR value?
Could you help check this case?
Thanks & Regards,
Ben
