101 / 144 page  101 TPS65911 www.ti.com SWCS049S – JUNE 2010 – REVISED AUGUST 2018 Submit Documentation Feedback Product Folder Links: TPS65911 Detailed Description Copyright © 2010–2018, Texas Instruments Incorporated Table 6-63. EN1_SMPS_ASS_REG Address Offset 0x46 Instance Reset Domain: TURNOFF RESET 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 Type RW 7 6 5 4 3 2 1 0 Reserved SPARE_EN1 VDDCTRL_ EN1 VDD2_EN1 VDD1_EN1 VIO_EN1 Bits Field Name Description Type Reset 7:5 Reserved RO R returns 0s 0x0 4 SPARE_EN1 Spare bit RW 0 3 VDDCTRL_EN1 When control bit = 1: When EN1 is high the supply voltage is programmed though VDDCtrl_OP_REG register, and it can also be programmed off. When EN1 is low the supply voltage is programmed though VDDCtrl_SR_REG register, and it can also be programmed off. When control bit = 0: No effect: Supply state is driven though registers programming and the device state RW 0 2 VDD2_EN1 When control bit = 1: 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 SLEEP_KEEP_RES_ON = 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 RW 0 1 VDD1_EN1 When 1: 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 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_EN1 When control bit = 1, supply state is driven by the SCLSR_EN1 control 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 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 |
