D.13 Mode O waveform
Hardware-Triggered Strobe with Edge Disarm
Mode O, shown in Figure O, is identical to Mode C except that the
counter will be disarmed while an inactive-going Gate edge is applied to
the counter. And the counter will hold the count value until it is issued a
LOAD command or REST command.
