D.1 Mode A waveform

Software-Triggered Strobe with No Hardware Gating

Mode A is one of the simplest operating modes. The counter will be

available for countering source edges when it is issued and ARM

command. On each TC the counter will reload from the Load register

and automatically disarm itself, inhibiting further counting. Counting

will resume when a new ARM command is issued.
