The following tables list the TPS65086470 device settings for the buck regulators (Table 7-17), general purpose LDOs (Table 7-18), VTT LDO (Table 7-19), load switches (Table 7-20), and GPOs (Table 7-21). LDOA1 is not used in sequence so all registers with LDOA1_SWB2 will function as LDOA1. Additionally, SWB1 and SWB2 are not merged so all registers with SWB2_LDOA1 will function as SWB2. All values which can be modified by I2C after power on are shown in italics. Additional details (such as GPO power good inputs) can be found in the register map.
