This sticky read-only bit indicates that the 3.3 V supply dropped below the 2.7 V level at some point. Once
set, this bit will remain set until a 1 is written to this bit position or a reset occurs. Writing a 0 will have no
effect.

Sticky 2.1 V Low Voltage Flag
This sticky read-only bit indicates that the 2.5 V supply dropped below the 2.1 V level at some point. Once
set, this bit will remain set until a 1 is written to this bit position or a reset occurs. Writing a 0 will have no
effect.

2.7 V Low Voltage Flag
This read-only bit indicates that the 3.3 V supply is currently below the 2.7 V level. This bit may reset itself
if the supply voltage rises above the threshold.

2.1 V Low Voltage Flag
This read-only bit indicates that the 2.5 V supply is currently below the 2.1 V level. This bit may reset itself
if the supply voltage rises above the threshold.

PS_STS field descriptions (continued)
When asserted, indicates that the supply voltage is too low for reliable operation.
Resets the power supervisor registers. This signal is usually derived from POR and
other device reset sources.
Used by the glitch filter during normal operation and by control registers at all times.
