SM0 Voltage Selection by SM0EN SM0 ACTIVE LEVEL SM0EN SM0 OUTPUT VOLTAGE 0 0 1.2V 0 1 OFF The SM0 output voltage value and transition is controlled by the SM0EN pin and SM0VS1/SMVS2. NOTE During a HI to LO transition of SM0EN (enabling SM0), the SM0 output will power up to the pre-defined default state regardless of the setting set via I 2C prior to SM0 being disabled. Table 3-22.

LDO4 Voltage Selection Register Settings LDO4 OUTPUT VOLTAGE SELECTION LDO4VS LDO4GO=1 STARTS VOLTAGE TRANSITION TO VALUE SET BY REGISTER 0 LDO4V1 1 LDO4V2 The LDO2 output voltage selection and GO bit functionality is shown below. 1. LDO2AGOn bits are not active 2. LDO2BGO1=1 starts a voltage transition to the voltage selected by LDO2BV1, LDO2BV2 and LDO2BVS1 3. LDO2 voltage transition starts when SM0EN is set to LO When the LDO2 output voltage is controlled by the SM0EN (CORECTRL) pin, registers LDO2AV2 and LDO2AV1 define the output voltage: DETAILED DESCRIPTION 56 Submit Documentation Feedback |
