Register Map
The “Register Map” tab enables reading and writing any
value to any register in the FUSB302. When performing a
register write, the selected register/registers is/are read back
again to confirm the write action. So the write button
actually performs a write and then a read operation.
The “Device Poll” option tells the GUI to automatically
check the DEVICE_ID register for the I2C address selected
in the “Addr” pull down box and display the “Device
Connected ...” or “ No Device” message in the lower left
corner of the GUI.
The “Register Poll” option tells the GUI to constantly poll
the FUSB302 registers and update the register values. This
should be used only for debugging since it can disrupt the
timing operations of the firmware and also can clear
interrupts that occur because the FUSB302 interrupt
registers are “Read to Clear”.
