Hello,

I am trying to change the VCCINT or the core voltage of a Xilinx ZCU104 board using an Infineon USB005 dongle.
For this, I am using the PowIRCenter software by Infineon and changing the VOUT_COMMAND in Switcher A which is set at 0.852V.
But, When I try to change the voltage it always gets automatically reduced by 4mV.
For example, if I write a value of 0.849V, it will show the value written is 0.848V (i.e. 0.852-0.848=4mV) or if I write a value of 0.845V
it will show written value is 0.844V.
This happens every time I try to change the voltage, it always gets reduced or changed in sizes of 4 mV.

I want to know if instead of 4, it is possible to reduce the voltage by 1 or 2mV. For example from 0.852V to 0.851V.

Thank you for any help and suggestion you can give. I really appreciate your time.
