8. Set the pulse width for the single-pulse generation. The following
example assumes a 10 MHz source (period = 100 ns) for counter 1.
Therefore, the pulse width is 100 ns × 500000 = 50 ms. If you use a
frequency other than 10 MHz, adjust the number accordingly. For a
frequency F, 1/F ×
ND_COUNT_2
should equal 50 ms.
9. Program counter 1 to perform single-pulse generation.
