When SCLSR_EN1 is high the supply voltage is programmed though
VDD2_OP_REG register, and it can also be programmed off.
When SCLSR_EN1 is low the supply voltage is programmed though
VDD2_SR_REG register, and it can also be programmed off.
When SCLSR_EN1 is low and VDD2_KEEPON = 1 the SMPS is working
in low power mode, if not tuned off through VDD2_SR_REG register.
When control bit = 0 no effect: supply state is driven though registers

signal and is also defined though SLEEP_KEEP_RES_ON register
setting:
When SCLSR_EN1 is high the supply is on,
When SCLSR_EN1 is low:
- the supply is off (default) or the SMPS is working in low power mode if
VIO_KEEPON = 1
When control bit = 0 no effect: SMPS state is driven though registers
programming and the device state

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
