Chapter 20 Pulse Width Modulator with Fault Protection (PMF15B6C) Module
20.2
The pulse width modulator has external pins named PWM0–5, FAULT0–3, and IS0–IS2.
20.2.1
PWM0–PWM5 are the output pins of the six PWM channels.
20.2.2
FAULT0–FAULT3 are input pins for disabling selected PWM outputs.
20.2.3
IS0–IS2 are current status pins for top/bottom pulse width correction in complementary channel operation
while deadtime is asserted.

GENERATOR 0
GENERATOR 1
PWM source selection is based
on a number of factors:
• State of current sense pins
• IPOL bit
• OUTCTL bit
• Center versus edge aligned
