3.5 PCLKSELx.1: Peripheral Clock Selection Registers must be set
3.6 MCPWM.1: Input pins (MCI0-2) on the Motor Control PWM peripheral
before enabling and connecting PLL0
Introduction:
A pair of bits in the Peripheral Clock Registers (PCLKSEL0 and PCLKSEL1) controls the
rate of the clock signal that will be supplied to APB0 and APB1 peripherals.
Problem:
If the Peripheral Clock Registers (PCLKSEL0 and PCLKSEL1) are set or changed after
PLL0 is enabled and connected, the value written into the Peripheral Clock Selection
Registers may not take effect. It is not possible to change the Peripheral Clock Selection
settings once PLL0 is enabled and connected.
Work-around:
Peripheral Clock Selection Registers must be set before enabling and connecting PLL0.
are not functional
Introduction:
On the LPC176x, 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.
Problem:
The input pins (MCI0-2) are not functional.
Work-around:
The GPIO interrupts on port 0 or port 2 can be used instead of the MCPWM MCI0-2 pins.
The GPIO interrupts give the ability to trigger an interrupt on both the rising and falling
edge; therefore, all six states of the connected hall sensor can be detected through an
interrupt.
