3.7 MCPWM.1: Input pins (MCI0-2) on the Motor Control PWM peripheral
are not functional
Introduction:
On the LPC3220, the Motor Control PWM (MCPWM) peripheral is optimized for
three-phase AC and DC motor control applications and can also be used in applications
which require timing, counting, capture, and comparison. The MCPWM contains three
input pins (MCI0-2) for PWM channels 0, 1, and 2. The inputs can be used as feedbacks
for controlling brushless DC motors with Hall sensors, and also can be used to trigger a
Timer/Counter’s (TC) capture or increment a channel’s TC when MCPWM is configured
as a timer/counter.
Note: MCI0-2 pins are also called MCFB0-2 (refer to LPC32x0 User manual for more
details).
Problem:
The input pins (MCI0-2) are not functional.
Work-around:
The GPIO interrupts
LPC3220, the GPIO interrupts can only be set to either trigger on the rising edge or on the
falling edge. Therefore, in order to detect all six states of the connected hall sensor
through an interrupt, the state of the pin needs to be determined and switch to rising or
falling edge interrupt accordingly.
