5.4 Counter/Timer Features

The PCI-1712/1712L features multifunction counter/timer functions with one-shot, rate generation, frequency measurement and pulse width measurement. There are two 8254 counter chips in PCI-1712/ 1712L, and each chip has 3 multifunction counters. The first counter chip (chip 1) is specified for AI and AO functions, and can’t be used by user. The second counter chip (chip 2) is reserved for user, and the following section describes its features.

The PCI-1712/1712L uses the 82C54 programmable timer/counter chip includes 3 independent 16-bit down counters: counter 0, counter 1 and counter 2. Each counter has clock input, gate input and pulse output. It can be programmed to count from 2 up to 65535.

Clock sources

The following clock sources are available for the user counters, and they are available to set its active edge as rising edge or falling edge:

qInternal clock

User can specify the internal clock as the clock source through software, and choose among four frequency options: 10MHz, 1MHz, 100kHz and 10kHz of the on-board crystal oscillator. For detailed information, please refer to Appendix D.14 Counter gate and clock control/status.

qExternal clock

The external clock is useful when you want to pace counter/timer operations at rates not available with the internal clock or if you want to pace at uneven internals. User can specify an external clock as the clock source through software. User could connect the external clock to the PCI-1712/1712L through the PCLD-8712 screw-terminal wiring board that corresponds to each counter/timer.

qInternally cascaded clock

You can also route the clock output signal from one user counter to the clock input signal of the next user counter to internally cascade the counters. In this way, you can create a 32-bit or even a 48-bit counter without externally cascading multiple counters together. When user wants to cascade the counters, please follow the round-robin order of
