The functional block diagram for the controller is shown to the right. The blocks are:
* '''19-cycle hold'''
* '''19-cycle hold'''
** Identical to the component of the same name in the DAC emulator (see above)

The functional block diagram for the emulator is shown to the right. The blocks are:
* '''Error Flag'''
** The error flag goes high if the enable line is high for 1-15 or 17+ cycles. It resets to low any time the enable line goes back to high. It is used to notify of a "bad" transmission (not 16 cycles long).
** inputs
*** ''Clk'': clock
*** ''Rst'': asynchronous, active-low reset
*** ''En'': enable
** outputs
*** ''Err'': error flag
