Button Descriptions
Read: Clicking on this button reads the ACT88420 registers and displays them in the GUI. Note that this reads
all registers. Active-Semi recommends reading registers each time the ACT88420 powers-up to acquire the
initial register settings. Qorvo also recommends reading registers after making changes to them. Immediately
reading the registers after a write confirms the changes were properly stored. This also updates the SYSTEM
STATUS box to ensure that one of the changes did not generate a fault condition.

Write: Clicking on this button writes the GUI settings to the ACT88420’s registers. All registers are written,
regardless of whether or not they were changed.
Note: Remember that changes to the GUI settings are not transferred into the IC until the GUI’s “Write” button
is pressed.
