** outputs
** outputs
*** ''Q'': three-bit data-out bus
*** ''Q'': three-bit data-out bus
* '''temperature register'''
** A ten-bit register to store the most recent temperature data.
** inputs
*** ''Clk'': clock
*** ''/Rst'': asynchronous, active-low reset to zero the register (puts system into reset state)
*** ''En'': write enable
*** ''D'': ten-bit data-in bus
** outputs
*** ''Q'': ten-bit data-out bus
* '''ADC registers'''
** A set of eight 12-bit registers to store the most recent ADC data. Also includes a demultiplexer to select which register to write to.
** inputs
