32-bit CPU-Timers 0/1/2 (continued)
In the F2810 and F2812 devices, the timer interrupt signals (TINT0, TINT1, TINT2) are connected as shown
in Figure 13.

NOTES: 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 13. 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 43 are used to configure the timers.
