TIMER/EVENT COUNTER PROGRAMMING MODEL

The DSP56367 views each timer as a memory-mapped peripheral with four registers
occupying four 24-bit words in the X data memory space. Either standard polled or interrupt
programming techniques can be used to service the timers. The timer programming model is
shown in Figure 13-3.
