The overvoltage (OV) monitoring threshold for the switching regulators is set in the OTP registers via the
OTP_SWx_OVTH[2:0] bits.

Table 157. SWx OV threshold configuration bits
For safety considerations, the OV/UV monitoring thresholds are selected in OTP during the part number
configuration phase, and they are not allowed to be changed during system operation. However, the system
can choose to open the monitoring range during the Monitored STANDBY state, to accommodate larger DC/AC
output voltage accuracy on the SWx regulators due to the PFM operation.
The SWx_UVTH_STBY and SWx_OVTH_STBY bits are provided to select whether to use the same OV/UV
monitoring threshold in RUN and STANDBY states or force the maximum OV/UV monitoring threshold during
the STANDBY state.
SWx_UVTH_STBY
UV threshold in STANDBY

Table 159. SWx OV threshold configuration bits during STANDBY
By default, the SWx_UVTH_STBY and SWx_OVTH_STBY bits are set to 1 at power up, and the MCU can
modify their values before requesting access to the STANDBY states.
The undervoltage monitoring threshold for the LDO regulators is set in the OTP registers via the
OTP_LDOx_UVTH[2:0] bits.
