Description
Configuration Register turning-off SMPS regulator during the SLEEP state of the device.

Physical Address
Instance
Description
Configuration Register setting the LDO regulators, driven by the multiplexed SCLSR_EN1 signal.
When control bit = 1, LDO regulator state is driven by the SCLSR_EN1 control signal and is also defined
though SLEEP_KEEP_LDO_ON register setting:
When SCLSR_EN1 is high the regulator is on,
When SCLSR_EN1 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
