The Gen. Purpose registers are read by the MPS430. When the MPS430 reads these
registers, it checks to see if they contain the values 0x0055 and 0x00AA. The MPS430 uses
this as a check to see if the FPGA has been configured and thus can determine the validity
of the other read data.
A MAX1617 temperature sensor is connected to the MPS430 to enable it to monitor the
FPGA’s core temperature.
Power Measurement
Several of the major power supplies can be measured using an 8 channel ADC which is part
of a micro-controller. The schematic is shown below.
