Explanation
Just as in the previous example, SMCLK is set to 1MHz. Timer_A3 is also setup for up counting with a
top value of 999, resulting in 1ms time duration. Note no interrupt is used and other CCR registers are
loaded with 10 – an arbitrary value.
/* TA0CCR0, Timer_A Capture/Compare Register 0 */
TA0CCR0 = 999;
/* TA0CCR1, Timer_A Capture/Compare Register 1 */
TA0CCR1 = 10;
/* TA0CCR2, Timer_A Capture/Compare Register 2 */
TA0CCR2 = 10;
/*
* TA0CTL, Timer_A3 Control Register
*
* TASSEL_2 -- SMCLK
* ID_0 -- Divider - /1
* MC_1 -- Up Mode
*/
TA0CTL = TASSEL_2 | ID_0 | MC_1;
