• When the VMON_EN bit of a specific regulator is 1, the voltage monitor for that specific

regulator is enabled.

• When the VMON_EN bit of a specific regulator is 0, the voltage monitor for that specific

regulator is disabled.

By default, the VMON_EN bits are set to 1 on power up.

When the I2C_SECURE_EN = 1, a secure write must be performed to set or clear the

VMON_EN bits to enable or disable the voltage monitoring for a specific regulator.

On enabling a regulator, the UV/OV monitor is masked until the corresponding regulator

reaches the point of regulation. If a voltage monitor is disabled, the UV_S and OV_S

indicators from that monitor are reset to 0.

15.6.1 Voltage monitoring architecture

Figure 31 shows the voltage monitoring architecture.
