Power Display (U28)
The power being measured by the MAX II CPLD and associated A/D is
displayed on a dedicated 7-segment display connected to the MAX II
device called Power Display. Although the 7-segment display is connected
to the MAX II CPLD, it is also register-controllable from the FPGA using
the FSM bus.
