CNTRL A (02h), CNTRL B (03h): Default 00h (Do not write to this register in direct mode)
Valid write commands:
00h – Force mode is enabled with all supplies disabled.
01h – Enable VAUXA/B supply with force mode.
02h – Enable main supplies with force mode.
03h – Enable main and VAUXA/B with force mode.
04h – Disable FORCEON pins with all supplies disabled.
05h – Enable VAUXA/B supply without force mode.
06h – Enable main supplies without force mode.
07h – Enable all supplies without force mode.
(A write to this register in direct mode switchs the TPS2363 to SMBus mode, it will not switch back until power is
cycled on the TPS2363.)
