Format
daq9513SetMasterMode (handle, deviceType, whichDevice, foutDiv,
cntSource, comp1, comp2, tod)
Purpose
daq9513SetMasterMode is used to set the counter’s master mode register, which is used to configure
the frequency output pin (P3 pin 30), the comparators of counter 1 and 2, and the time-of-day operation of
the 9513 chip.
