130h
SMPS4_CTRL
SMPS4 control register.
RESET register domain: HWRST (MODE_ACTIVE and
MODE_SLEEP are in SWORST domain)
Notes: MODE_SLEEP is used when NSLEEP,
ENABLE1, ENABLE2 signals select the resource.
MODE_ACTIVE is used when none of NSLEEP,
ENABLE1, ENABLE2 signals select resource (see
Resources SLEEP/ACTIVE assignments table in the
Data Manual for details).
133h
SMPS4_VOLTAGE
SMPS4 register.
Voltage to apply to the resource.
RESET register domain: SWORST
138h
SMPS5_CTRL
SMPS5 control register.
RESET register domain: HWRST (MODE_ACTIVE and
MODE_SLEEP are in SWORST domain)
Notes: MODE_SLEEP is used when NSLEEP,
ENABLE1, ENABLE2 signals select the resource.
MODE_ACTIVE is used when none of NSLEEP,
ENABLE1, ENABLE2 signals select resource (see
Resources SLEEP/ACTIVE assignments table in the
Data Manual for details).
13Bh
SMPS5_VOLTAGE
MPS5 register.
Voltage to apply to the resource.
RESET register domain: SWORST
144h
SMPS_CTRL
SMPS control register.
RESET register domain: HWRST
145h
SMPS_PD_CTRL
SMPS Pull-Down enable register.
RESET register domain: HWRST
Notes:
SMPS pull-down register bits validate the control of the
active discharge of each power resource to full-fill the
turn-off timing requirements.
When a pull-down is not enabled, there is always a weak
pull-down present at the output of the power resource,
so that the device restart correctly at the next power-up
sequence.
