Configuration Registers

10.14.1

APPLIED CURRENT LIMITING

BEHAVIOR REGISTER

The Applied Current Limiting Behavior Register stores

the values used by the applied current limiting mode

(Trip or CC) when the custom settings are not used.

The contents of this register are automatically updated

when charger emulation is completed.
