VDDCRTL_REG Address Offset 0x27 Physical Address Instance (RESET DOMAIN: TURNOFF OFF RESET) Description VDDCtrl, external FET controller Type RW 7 6 5 4 3 2 1 0 Reserved ST Bits Field Name Description Type Reset 7:2 Reserved Reserved bit RO R returns 0s 0x00 1:0 ST Supply state (EEPROM dependent): ST[1:0] = 00: Off ST[1:0] = 01: On ST[1:0] = 10: Off ST[1:0] = 11: On RW 0x0 Table 6-43. VDDCRTL_OP_REG Address Offset 0x28 Physical Address Instance (RESET DOMAIN: TURN OFF RESET) Description VDDCtrl voltage selection register. This register can be accessed by both control and voltage scaling dedicated I2C interfaces depending on SR_CTL_I2C_SEL register bit value. Type RW 7 6 5 4 3 2 1 0 CMD SEL Bits Field Name Description Type Reset 7 CMD Command: when 0: VDDctrl_OP_REG voltage is applied when 1: VDDctrl_SR_REG voltage is applied RW 0 6:0 SEL Output voltage (4 EEPROM bits) selection: SEL[6:0] = 1000011 to 1111111: 1.4 V ... SEL[6:0] = 0110011: 1.2 V ... SEL[6:0] = 0010011: 0.8 V ... SEL[6:0] = 0000001: 0000011 0.6 V SEL[6:0] = 0000000: Off (0.0 V) Note: from SEL[6:0] = 3 to 64 (dec) Vout = (SEL[6:0] × 12.5 mV + 0.5625 V) (Default value: See boot configuration) RW 0x00 Table 6-44. VDDCRTL_SR_REG Address Offset 0x29 Physical Address Instance (RESET DOMAIN: TURN OFF RESET) Description VDDCtrl voltage selection register. This register can be accessed by both control and voltage scaling dedicated I2C interfaces depending on SR_CTL_I2C_SEL register bit value. Type RW |
