Physical Address

Description
Configuration Register setting the LDO regulators, driven by the EN3 signal.
When control bit = 1, LDO regulator state is driven by the EN3 control signal and is also defined though
SLEEP_KEEP_LDO_ON register setting:
When EN3 is high the regulator is on,
When EN3 is low:
- the regulator is off if its corresponding Control bit = 0 in SLEEP_KEEP_LDO_ON register
- the regulator is working in low power mode if its corresponding control bit = 1 in
SLEEP_KEEP_LDO_ON register
When control bit = 0 no effect: LDO regulator state is driven though registers programming and the
device state.
