where
• the ^ symbol indicates a logical exclusive OR (XOR) function
• the & symbol indicates a logical AND function
• the | symbol indicates a logical OR function
• the ! symbol indicates a logical NOT function
The combinations of polarity, enable, and PWM signals allow the logic to generate a
ADC-trigger under a wide variety of operating conditions. The HEN, LEN, nHEN, and
nLEN bits enable a group in the or logic. The CSTWMx bits allow the level of the PWM
output signals to control the equation. If a CSTPWMx bit is cleared, the value of the asso-
ciated PWMx output will always evaluate to a TRUE condition in the equation. Note that
these bits DO NOT affect the actual PWM outputs.
