DATASHEET
The Preloaded Emulation Configuration registers store the settings loaded from internal memory as
required for the preloaded charger emulation profile that is actively being applied. These registers are
read only.
10.12.1
Applied Charger Emulation - 30h
The contents of this register are not retained in Sleep. The contents are updated as the charger
emulation profile being applied changes.
Bits 3 - 0 - PRE_EM_SEL[3:0] - Indicates which of the charger emulation profiles is being actively
applied as shown in Table 10.26.
10.12.2
Preloaded Emulation Configuration Registers 31h - 3Bh
These registers store the emulation configuration settings for the currently applied preloaded charger
emulation profile. The contents of these registers 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.
