The VMU has a fixed Over Voltage threshold, however the Under Voltage threshold has two settings for each VDD_INT and VDD_EXT. The register REFPRG is responsible for programming the Under Voltage threshold. It is located in the PADS_VMU_CRL.REFPRG register set.

 

The following tables shows the programmable values for the under threshold voltage:

 

VDD_EXT Out of Range Threshold

Threshold
Min (V)Typical (V)
Max (V)
REFPRG<1>
OVLO_E3.563.593.62-
UVLO_E12.942.973.00
UVLO_E22.772.802.831
