ADuC7023
On power-up, PWMCON1 defaults to 0x0012 (HOFF = 1 and
HMODE = 1). All GPIO pins associated with the PWM are
configured in PWM mode by default (see Table 85). Clear the
PWM trip interrupt by writing any value to the PWMCLRI

MMR. Note that when using the PWM trip interrupt, clear the
PWM interrupt before exiting the ISR. This prevents generation
of multiple interrupts.
