Table 176. VLDOxMON monitoring voltage configuration bits...continued

In applications where the monitored output require dynamic voltage scaling during the system operation, the

MCU must manage the voltage transitions in a safe way at system level.

In order to manage dynamic transition of the external voltage, the VLDOxMON block provides a programmable

masking timer to prevent OV/UV conditions from happening during the external voltage transition.

When the VLDOxMON voltage selection is changed from one set point to another, the VLDOxMON will mask

the OV and UV fault monitoring for a period of time defined by the VLDOxMON_TMASK[1:0] bits. The default

value for the masking timer is set in OTP registers via the OTP_VLDOxMON_TMASK[1:0] bits.
