General Purpose Digital Counter

The U2300A series DAQ device has two independent 31–bit up/down counters to
measure the input channels, which are TTL compatible. It has a programmable
counter clock up to 12 MHz or clock generation. Refer to
illustration.
The counter is designed with the following features:
– Count up/down capability
– Internal/external programmable counter clock source up to 12 MHz
– Programmable gate selection which can be triggered internally or externally
– Pre-loaded software initial count for totalizer
– Read-back capability of current count, without affecting the counting process
This digital counter operates in two modes: totalizer and measurement modes. In
either measurement mode or totalize mode, the signal source should be
connected to the pin COUNT_GATE. In measurement mode, the signal that goes
through the COUNT_GATE is the signal users wish to measure. In totalize mode,
the signal that goes through the COUNT_GATE is the signal that enables the
counter to start counting the clock.
