Register Descriptions
3.4.3.1
Register Settings
Within the power supply control register (PWD_CTL, *_RAMMODE_SEL, ANA_PW_CTL), there is a Write
Enable for each power supply. Power supply control is enabled only for power supplies with Write Enable set to
“1”, allowing the control of the desired power supply without performing read-modify-write.
When making the settings for power supply control, make sure to use Word access to simultaneously perform
write operations to the bits of Write Enable and each power supply’s setting (ON/OFF). Do not use Byte or half
word access.
3.4.3.2

Table PMU (Power Management Unit)-37 and Table PMU (Power Management Unit)-38 show the registers
