EN2_SMPS_ASS_REG Address Offset 0x48 Physical Address Instance (RESET DOMAIN: TURNOFF RESET) 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 Type RW 7 6 5 4 3 2 1 0 Reserved SPARE_EN2 VDDCTRL_ EN2 VDD2_EN2 VDD1_EN2 VIO_EN2 Bits Field Name Description Type Reset 7:5 Reserved RO R returns 0s 0x0 4 SPARE_EN2 Spare bit RW 0 3 VDDCTRL_EN2 When control bit = 1: When EN2 is high the supply voltage is programmed though VDDCtrl_OP_REG register, and it can also be programmed off.. When EN2 is low the supply voltage is programmed though VDDCtrl_SR_REG register, and it can also be programmed off. When EN2 is low and VDDCtrl_KEEPON = 1 the SMPS is working in low-power mode, if not tuned off though VDDCtrl_SR_REG register. When control bit = 0 no effect: Supply state is driven though registers programming and the device state RW 0 2 VDD2_EN2 When control bit = 1: 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 SLEEP_KEEP_RES_ON = 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 RW 0 1 VDD1_EN2 When control bit = 1: 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 SLEEP_KEEP_RES_ON = 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 RW 0 0 VIO_EN2 When control bit = 1, 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 its corresponding control bit = 1 in SLEEP_KEEP_RES_ON register When control bit = 0 no effect: SMPS state is driven though registers programming and the device state RW 0 Table 6-66.
