LDO_PD_CTRL1
LDO Pull-Down enable register #1
RESET register domain: HWRST
NOTES:
LDO pull-down enable register bits validate the control of
the active discharge of each power resource to fulfill 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 restarts correctly at the next power-up
sequence.

LDO_PD_CTRL2
LDO Pull-Down enable register #2
RESET register domain: HWRST
NOTES:
LDO pull-down enable register bits validate the control of
the active discharge of each power resource to fulfill 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 restarts correctly at the next power-up
sequence.
