Triple Timer Module
9.1.2 Individual Timer Block Diagram
Figure 9-2 shows the structure of an individual timer block. The DSP56309 treats each timer as a
memory-mapped peripheral with four registers occupying four 24-bit words in the X data
memory space. The three timers are identical in structure and function. Either standard polled or
interrupt programming techniques can be used to service the timers. A single, generic timer is
discussed in this chapter. Each timer includes the following:
The timer mode is controlled by the TC[3–0] bits which are TCSR[7–4]. For a listing of the timer
modes and descriptions of their operations, see Section 9.3, Operating Modes, on page 9-5.
