func
Determines the function performed by the marker processor. When high, each marker
circuit within the processor will locate an accumulated count from the ACC RAM
corresponding to the previously given grey value. When low, each marker will locate the
grey value corresponding to a previously given accumulation count from the ACC RAM.
pdwn
When high, the ACC and LUT RAMs are placed in an inactive mode. Should be low for
normal operation.
