VDD1_OP_REG Address Offset 0x22 Instance Reset Domain: TURNOFF OFF RESET Description VDD1 voltage selection register. This register can be accessed by both control and voltage scaling 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 when 0: VDD1_OP_REG voltage is applied when 1: VDD1_SR_REG voltage is applied RW 0 6:0 SEL Output voltage (4 EEPROM bits) selection with GAIN_SEL = 00 (G = 1, 12.5 mV per LSB): SEL[6:0] = 1001011 to 1111111: 1.5 V ... SEL[6:0] = 0111111: 1.35 V ... SEL[6:0] = 0110011: 1.2 V ... SEL[6:0] = 0000001 to 0000011: 0.6 V SEL[6:0] = 0000000: Off (0.0 V) Note: from SEL[6:0] = 3 to 75 (dec) Vout = (SEL[6:0] × 12.5 mV + 0.5625 V) × G (Default value: See boot configuration) Note: Vout maximum value is 3.3 V RW 0x00 Table 6-38. VDD1_SR_REG Address Offset 0x23 Instance Reset Domain: TURNOFF OFF RESET Description VDD1 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 Reserved SEL Bits Field Name Description Type Reset 7 Reserved Reserved bit RO R returns 0s 0 6:0 SEL Output voltage selection with GAIN_SEL = 00 (G = 1, 12.5 mV per LSB): SEL[6:0] = 1001011 to 1111111: 1.5 V ...
