PMC Memory Map/Register Definition
14.4.3 Regulator Status and Control Register (PMC_REGSC)
The power management controller contains an internal voltage regulator. The voltage
regulator design uses a bandgap reference, that is also available through a buffer as input
to certain internal peripherals. The internal regulator provides a status bit (REGONS)
indicating the regulator is in run regulation. This bit is used when the application moves
from a low power or very low power mode where the frequency is limited to normal run
mode. The frequency of the application can not be increased until the regulator is back in
run regulation (REGONS=1).
Address: PMC_REGSC is 4007_D000h base + 2h offset = 4007_D002h
