be read back on all channels and a software compare performed on the digital
data.  Using this scheme all R/D converters can be tested in the same software test
loop.  The reader should refer to Section 4 for additional programming details.  A
front panel Fail LED is initialized on during power-up reset and may be
extinguished via program control upon successful completion of diagnostics.
Because this product is designed to utilize the DC reference voltage from channel 0
for the test signal input to all four modules, this functional test is accurate to within
20 counts (the user should expect a 20-count error).

PITCH COUNTER OPERATION

The 16-bit pitch counters utilize the direction and carry outputs from the

R/D modules to count the number of revolutions.  Control logic is provided (refer to
Figure 3.6-1) to ensure synchronous writing/reading/counting.
