Active-semi ACT2861EVK1-201 User Manual page 19

Button Descriptions
Read: Clicking on this button reads the ACT2861 registers and displays them in the GUI. Note that this reads
all registers. Active-Semi recommends reading registers each time the ACT2861 powers-up to acquire the initial
register settings. Active-semi also recommends reading registers after making changes to them. Immediately
reading the registers after a write confirms the changes were properly stored.
Write: Clicking on this button writes the GUI settings to the ACT2861's registers. All registers are written,
regardless of whether or not they were changed.
Dongle Connection Status: The GUI also contains a dongle connection status that indicates Active-Semi's
USB-TO-I2C dongle is connected to the USB port. The figure below shows the two possible indication status
graphics.
