11.3 Timer/Event Counter Programming Model
The DSP56366 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 11-3
