Figure 12. OCFG = 11
The STA559BW can be configured to support different output configurations. For each PWM
output channel a PWM slot is defined. A PWM slot is always 1 / (8 * fs) seconds length. The
PWM slot define the maximum extension for PWM rise and fall edge, that is, rising edge as
far as the falling edge cannot range outside PWM slot boundaries.
Figure 13. Output mapping scheme
For each configuration the PWM signals from the digital driver are mapped in different ways
to the power stage:
