System Control and Interrupts
Figure 1-32. CPU-Timer Interrupt Signals and Output Signal
A The timer registers are connected to the Memory Bus of the 28x processor.
B The timing of the timers is synchronized to SYSCLKOUT of the processor clock.
The general operation of the CPU timer is as follows: The 32-bit counter register TIMH:TIM is loaded with
the value in the period register PRDH:PRD. The counter decrements once every (TPR[TDDRH:TDDR]+1)
SYSCLKOUT cycles where TDDRH:TDDR is the timer divider. When the counter reaches 0, a timer
interrupt output signal generates an interrupt pulse. The registers listed in Table 1-31 are used to
configure the timers.
