Power Drive Protection
The PDPINTx is a safety feature that is provided for the safe operation of systems such as power
converters and motor drives.
PDPINTx can be used to inform the monitoring program of motor
drive abnormalities such as overvoltage, over-current, and excessive temperature rise. If the
PDPINTx interrupt is unmasked, all PWM output pins will be put in the high-impedance state
immediately after the
PDPINTx pin is driven low. An interrupt will also be generated.
