TMP92CF26A is provided with the following six power supply rails.
external pins (DVCC-3A, DVCC-3B), AD converter (AVCC) and RTC and backup RAM
(DVCC-1B). After entering this mode, internal signals that communicate with the circuit blocks
powered by DVCC1A and DVCC1C are cut off so that no shoot-through current is generated in
the circuitry when the power is removed from those blocks.

The TMP92CF26A incorporates the power management circuitry (PMC) for managing
Each power supply rail is independent of one another (VSS is partially shared).
Among the six power supply rails, those that are supplied in Power Cut mode are the ones for
