Bit 7 – VLMF VLM Flag

This bit is set by the VLM circuit to indicate that a voltage level condition has been triggered. The bit is cleared when the trigger level selection is set to “Disabled”, or when voltage at VCC rises above the selected trigger level.

Bit 6 – VLMIE VLM Interrupt Enable

When this bit is set the VLM interrupt is enabled. A VLM interrupt is generated every time the VLMF flag is set.

Bits 2:0 – VLM[2:0] Trigger Level of Voltage Level Monitor

These bits set the trigger level for the voltage level monitor.
