In the F281x and C281x devices, the timer interrupt signals (TINT0, TINT1, TINT2) are connected as shown
in Figure 42.

Figure 42. CPU-Timer Interrupts Signals and Output Signal (See Notes A and B)
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 41 are used to configure the timers. For more information, see the TMS320x281x System Control
and Interrupts Reference Guide (literature number SPRU078).
