¶ General Description
A rectangular pulse generator with a period equal to the sum of the variables duration hi and duration lo.
When the input enable is a logical 0, the generator is off, and all outputs are set to zero.
When the input enable is a logical 1, the generator operates as follows:
- The counters
count hiandcount loalternate counting from zero up to the values ofduration hiandduration lo, respectively.- While the
count hicounter is active, theoutputis 1. - While the
