PWM Signal Generator
The PWM generator takes these pulses (qualified by the direction signal), and generates two PWM
signals. In Count-Down mode, there are four events that can affect the PWM signal: zero, load,
match A down, and match B down. In Count-Up/Down mode, there are six events that can affect
the PWM signal: zero, load, match A down, match A up, match B down, and match B up. The match
