In the F281x and C281x devices, the timer interrupt signals (TINT0, TINT1, TINT2) are connected as
shown in Figure 4-2.
A. The timer registers are connected to the memory bus of the C28x processor.
B. The timing of the timers is synchronized to SYSCLKOUT of the processor clock.
Figure 4-2. CPU-Timer Interrupts Signals and Output Signal
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 4-1 are used to configure the timers. For more information, see the TMS320x281x
DSP System Control and Interrupts Reference Guide (literature number SPRU078).
