3.10 ARRAY BUTTONS
The array buttons, which are located below the GUI Security register, allow the user to
perform read and write operations to the Serial EEPROM, navigate to specific word
addresses in the GUI memory array and also provides various support functions.

ARRAY BUTTONS
3.10.1
Refresh
The
Refresh
button reads the Serial EEPROM memory array of the installed device
and then populates the GUI memory array with that data. If there is data in the internal
GUI buffer (
green
font in cell) when the Refresh feature is used, that data will be
replaced with the data read from the Serial EEPROM. After the completion of any write
operation to the Serial EERPOM, the GUI will automatically update the GUI memory
array and Security register using the Refresh feature.

GUI memory array.

GO TO ADDRESS
Note:
If a new device is installed while leaving the USB Base Board connected to
the user’s PC, it is recommended to use the Device Query feature instead
of the Refresh feature to ensure robust GUI operation.
Note:
The Go To Address feature only works for addresses within the GUI mem-
ory array.
