NXP LPC32xx Motor Control PWM has an interrupt line shared with TIMER4, and the interrupt may be used to report events from programmable counters e.g. timer counter limit (period), match counter (pulse-width), or from counters on input lines of PWM channels. As a reference and for more details see NXP LPC32xx User Manual, table 595.

Properties must be defined in top-level. You only narrow constraints or disallow them :false per variant in if:then: blocks. Best regards, Krzysztof
