The Motor control PWM is available on all LPC18xx parts.
The PWM is configured as follows:
Table 546. PWM clocking and power control
The Motor Control PWM (MCPWM) is optimized for three-phase AC and DC motor control
applications, but can be used in many other applications that need timing, counting,
capture, and comparison.
The MCPWM contains three independent channels, each including:
Input pins MCI0-2 can trigger TC capture or increment a channel’s TC. A global Abort
input can force all of the channels into “A passive” state and cause an interrupt.
