STA333BWQS
Note:
Figure 9.
Figure 11. OCFG = 10
To the left of the arrow is the processing channel. When using channel output mapping, any
of the three processing channel outputs can be used for any of the three inputs.
STA333BWQS can be configured to support different output configurations. For each PWM
output channel a "PWM slot" is defined. PWM slot is always 1 / (8 x 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.
