Bit Description

2charger_lock

Enables lock of the charger registers 81h, 82h, 83h, 84h

Chargervoltagecontrol, Chargercurrentcontrol,

Chargerconfig1, Chargerconfig2 Bits can only be set. Reset

only with full reset cycle

1:0

reg_lock

b00

Enables lock of Regulator voltages Bits can only be set.

Reset only with full reset cycle Disable write to testmodes

registers if LDO_lock>0 writing stepdown voltage to 0

should be possible all the time to allow switching ON the

regulator. Writing a nonzero value after that should

restore the old value

0 : No lock

1 : Lock of voltage of LDOs (LDOx_vsel) (all bits) and

voltage of StepDownBits(sdx_vsel) [5:6] only

2 : Lock voltage of StepDownBits(sdx_vsel) [5:6] only

3 : Lock voltage of StepDown (all bits) and LDOs (all bits).
