8.6.6.1.2 IIN_DPM Register With 10-mΩ Sense Resistor (I2C address = 25/24h) [reset = 0h]
IIN_DPM register reflects the actual input current limit programmed in the register, either from host or from ICO.
After ICO, the current limit used by DPM regulation may differ from the IIN_HOST register settings. The actual
DPM limit is reported in REG0x25/24(). The register offset is 50 mA. With code 0, the input current limit read-
back is 50 mA.
