Physical Address

Description
Configuration Register setting the LDO regulators, driven by the multiplexed SDASR_EN2 signal.
When control bit = 1, LDO regulator state is driven by the SDASR_EN2 control signal and is also
defined though SLEEP_KEEP_LDO_ON register setting:
When SDASR_EN2 is high the regulator is on,
When SCLSR_EN2 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
Any control bit of this register set to 1 will disable the I2C SR Interface functionality

Description
Configuration Register setting the SMPS Supplies driven by the multiplexed SDASR_EN2 signal.
When control bit = 1, SMPS Supply state and voltage is driven by the SDASR_EN2 control signal and is
also defined though SLEEP_KEEP_RES_ON register setting.
When control bit = 0 no effect: SMPS Supply state is driven though registers programming and the
device state
Any control bit of this register set to 1 will disable the I2C SR Interface functionality

When SDASR_EN2 is high the supply is on.
When SDASR_EN2 is low and SLEEP_KEEP_RES_ON = 0 the supply
voltage is off.
When SDASR_EN2 is low and SLEEP_KEEP_RES_ON = 1 the SMPS
is working in low power mode.
When control bit = 0 no effect: supply state is driven though registers
programming and the device state
