// MSP430G2231 Demo - Timer_A, PWM TA1, Up Mode, SMCLK 
//
// Description: This program generates one PWM output on P1.2 using
// Timer_A configured for up mode. The value in CCR0, 1000-1, defines the
// PWM period and the value in CCR1 the PWM duty cycles. Using SMCLK,
// the timer frequenciy is about 1.1kHz with a 25% duty cycle on P1.2.
// Normal operating mode is LPM0.
// MCLK = SMCLK = default DCO (about 1.1MHz).
