•

Click on the row for the

DEFDCDC1

register (0x0E) again, and this time move the slider on the right-

hand side of the window to change the output voltage of DCDC1 to a new value. Write the new value
of this register by clicking the button labeled

W

in this row of the register map table, as shown in

. The value in the

PASSWORD

register (0x10) will also change because the IPG-UI is

automatically writing the correct password to this register in advance so that the DCDC1 register will
accept the new data.
