Mode 4 (software trigger strobe)
The counter output is switched to “H” level by the mode setting. Counting is started in the
same way as described for mode 0. A single “L” pulse equivalent to one clock width is
generated at the counter output when the terminal count is reached.
This mode differs from 2 in that the “L” level output appears one clock earlier in mode 2, and
that pulses are not repeated in mode 4. Counting is stopped when the gate input is switched
to “L” level, and restarted from the set count value when switched back to “H” level.
Mode 5 (hardware trigger strobe)
The counter output is switched to “H” level by the mode setting. Counting is started, and the
gate input used, in the same way as in mode 1.
The counter output is identical to the mode 4 output.
The various roles of the gate input signals in the above modes are summarized in the following
table.
