1) Register Details
This register sets the output current reference value (Digital CC).
The reference value is handled as Q10 format data normalized by the maximum current.
Digital CC is not referenced when analog CC is selected.
Configuration data is retained even when input is cut off.

*An exception response (Exception code: 0x03) is returned when writing values outside the range.
The specification range of the CC reference value is 0.2 - 1.15 .
This register can also input out of range. However, the current ripple may increase.
Refer to the instruction manual for setting CC reference value.
The CC reference change is influenced by the slew rate setting register, not the step change.
Slew rate setting register : [#12 Rising Time of Output Current]、[#14 Charging Time of Output Current at steady state]
The output voltage may not follow the CC reference because it is affected by the load impedance.
