STA335BWSQS
Figure 9.
Figure 11. OCFG = 10
STA335BWSQS can be configured to support different output configurations. For each
PWM output channel a PWM slot is defined. The PWM slot always has a time duration of
1/(8 * Fs) seconds. The PWM slot defines the maximum extension for PWM rising and
falling edges, that is, rising edge as far as the falling edge cannot range outside PWM slot
boundaries.
