#define PWM BIT6

// Description: This program generates one PWM output on P1.2 or P1.6 using
// Timer_A configured for up mode. The value in CCR0, 25-1, defines the PWM
// period and the value in CCR1 the PWM duty cycles.
// A 50% duty cycle on P1.6.
// ACLK = na, SMCLK = MCLK = TACLK = default DCO
