Address Offset 0x46
Physical Address Instance
Description Configuration Register setting the SMPS Supplies driven by the multiplexed SCLSR_EN1 signal.
When control bit = 1, SMPS Supply state and voltage is driven by the SCLSR_EN1 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

Bits Field Name Description Type Reset
7:5 RSVD Reserved bit RW 0
4 SPARE_EN1 Spare bit Rw 0
3 VDD3_EN1 When 1: RW 0
When SCLSR_EN1 is high the supply is on.
When SCLSR_EN1 is low and SLEEP_KEEP_RES_ON = '0' the supply
voltage is off.
When SCLSR_EN1 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
2 VDD2_EN1 When control bit = 1: RW 0
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
programming and the device state
1 VDD1_EN1 When 1: RW 0
When SCLSR_EN1 is high the supply voltage is programmed though
VDD1_OP_REG register, and it can also be programmed off.
When SCLSR_EN1 is low the supply voltage is programmed though
VDD1_SR_REG register, and it can also be programmed off.
When SCLSR_EN1 is low and VDD1_KEEPON = 1 the SMPS is working
in low power mode, if not tuned off though VDD1_SR_REG register.
When control bit = 0 no effect: supply state is driven though registers
programming and the device state
0 VIO_EN1 When control bit = 1, supply state is driven by the SCLSR_EN1 control RW 0
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
