In R281x devices, the timer interrupt signals (TINT0, TINT1, TINT2) are connected as shown in Figure 4−2.

INT1

INT12

INT14

C28x

TINT2

TINT0

PIE

CPU-TIMER 0

CPU-TIMER 2

Reserved RTOS

(DSP/BIOS)

INT13

TINT1

CPU-TIMER 1

XINT13

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 4−2. 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 4−1 are used to configure the timers. For more information, see the TMS320F28x System Control

and Interrupts Reference Guide

(literature number SPRU078).
