6.2.2 32-Bit CPU-Timer 0, CPU-Timer 1, CPU-Timer 2

There are three 32-bit CPU-timers on the devices (CPU-Timer 0, CPU-Timer 1, CPU-Timer 2).

CPU-Timer 2 is reserved for DSP/BIOS or SYS/BIOS. CPU-Timer 0 and CPU-Timer 1 can be used in user applications. These timers are different from the timers that are present in the ePWM modules.

NOTE

If the application is not using DSP/BIOS or SYS/BIOS, then CPU-Timer 2 can be used in the application.

The timer interrupt signals (TINT0, TINT1, TINT2) are connected as shown in Figure 6-3.

TMS320C28346 TMS320C28345 TMS320C28344 TMS320C28343 TMS320C28342 TMS320C28341 ai_intsig_prs439.gif
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 6-3 CPU-Timer Interrupt 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 6-2 are used to configure the timers. For more information, see the TMS320x2834x Delfino System Control and Interrupts Reference Guide.
