Explanations:
1. The instruction counts the number of pulses received at input terminal S
and stores the result in the register D.
2. ES2/EX2 before V0.92. External pulse input terminals designated in S
Available

5. D occupies 5 consecutive registers, D + 1 and D store the results of previous pulse detection; D
+3 and D + 2 store the current accumulated number of pulses; D + 4 store the current time
remaining (max. 32,767ms).
