These registers are read only. The contents of registers 31h-3Bh are loaded dynamically during charger emulation. When the Custom charger emulation profile is being applied, the contents of these registers will remain set at the previously applied preloaded charger emulation profile. The Legacy charger emulation profiles, and the BC1.2 DCP charger emulation profile do not use the Stimulus 3 Configuration registers (39h-3Bh). Whenever these charger emulation profiles are applied, registers 39h3Bh will not be updated and their contents should be ignored. The contents of registers 31h, 35 and 39h are not retained in Sleep. They are updated as needed. The contents of registers 32h, 33h, 34h, 36h, 37h, 38h, 3Ah, 3Bh, are retained in Sleep.
