CTS9513-2

5 Chan 16 bit 20MHz Counter/Timer

MODE G SOFTWARE TRIGGERED

DELAYED PULSE ONE-SHOT

In Mode G, once the counter has been ARMed, the

counter will:

Count to TC with the Load register value

Reload itself automatically from the Hold

Count to TC with the Hold Register Value

Disarm itself and reload the counter with

the Load register Value.

This produces a waveform as illustrated in Figure 16

in which the counter can in TC mode produce a pair

of pulses with the first pulse delay controlled by the

Load count value and the delay between the pulses

determined by the Hold register count.

If the Toggle Output mode is selected, the output

produced is a pulse width determined by the Hold

count and an initial delay determined by the Load

count. This is the more common use of this mode of

operation.

MODE H SOFTWARE TRIGGERED

DELAYED PULSE ONE-SHOT WITH

HARDWARE GATING

Mode H is similar to Mode G with the exception that

the counter is active only after receipt of an ARM

command and a valid Gate input. As shown in Figure

17 the counter counts only as long as the Gate line is

asserted and suspended while the Gate line is de-

asserted. Tas in Mode G the counter counts to TC

using the Load register value, reloads from the hold

counter reaches the second TC the counter disarms

itself and awaits another ARM command.

This mode allows extension of either the initial delay

or the delayed pulse width by use of the Gate.
