The general operation of the timer is as follows: The 32-bit counter register TIMH:TIM is loaded with the value in the period register PRDH:PRD. The counter register, decrements at the SYSCLKOUT rate of the C28x. When the counter reaches 0, a timer interrupt output signal generates an interrupt pulse. The registers listed in Table 4-1are used to configure the timers. For more information, see the TMS320x281x System Control and Interrupts Reference Guide (literature number SPRU078).
