55 / 104 page  3.54.3 DVM SUPPLIES - VOLTAGE TRANSITION CONTROL TPS658620 Advanced Power Management Unit www.ti.com SLVS993 – OCTOBER 2009 Table 3-18. SM0-2, LDO0-9 Control (continued) FORCE ENABLE TRANSITION REBOOT When 1 ON ON ENABLED 5ms SET SLEEP NORMAL TO NORMAL REQUEST MODE STATE LDO5 and LDO9 will be turned on when LDO5_ON is 1 or LDO9_ON is 1, respectively. The RTC_OUT LDO enable bits are located in the RTC control register, see real time clock section for details. The supply enable defaults are unique for each device. See App Notes for device specific settings. The output voltage for the DVM supplies can be set to one of the values programmed in the voltage setting registers SM0V1, SM0V2, SM1V1, SM2V2, LDO2AV1, LDO2AV2, LDO2BV1, LDO2BV2, LDO4V1 and LDO4V2 in registers VCC1 and VCC2. The voltage change for the DVM supplies is usually done with 2 I2C write commands: 1. The host writes the new voltage to the voltage setting register for the supply(s) that will have an output voltage modification. 2. The voltage change starts by setting specific control bits in registers VCC1 and VCC2. Bits VS in registers VCC1 and VCC2 select the next voltage for the DVM supplies. A voltage change is started when ANY of the GO bits for the supply is set to 1. At the end of the voltage transition the GO bits are cleared by the internal logic. Table 3-19.
