Table 6-60. EN2_SMPS_ASS_REG
Address Offset 0x48
Physical Address Instance
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

4 SPARE_EN2 Spare bit RW 0
3 VDD3_EN2 When 1: RW 0
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
2 VDD2_EN2 When control bit = 1: RW 0
When SDASR_EN2 is high the supply voltage is programmed though
VDD2_OP_REG register, and it can also be programmed off.
When SDASR_EN2 is low the supply voltage is programmed though
VDD2_SR_REG register, and it can also be programmed off.
When SDASR_EN2 is low and and VDD2_KEEPON = 1 the SMPS is
working in low power mode, if not tuned off though VDD2_SR_REG
register.
When control bit = 0 no effect: supply state is driven though registers
programming and the device state
1 VDD1_EN2 When control bit = 1: RW 0
When SDASR_EN2 is high the supply voltage is programmed though
VDD1_OP_REG register, and it can also be programmed off.
When SDASR_EN2 is low the supply voltage is programmed though
VDD1_SR_REG register, and it can also be programmed off.
When SDASR_EN2 is low and 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_EN2 When control bit = 1, RW 0
supply state is driven by the SCLSR_EN2 control signal and is also
defined though SLEEP_KEEP_RES_ON register setting:
When SDASR _EN2 is high the supply is on,
When SDASR _EN2 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
