Triple Timer Module
The timers in the DSP56309 internal triple timer module act as timed pulse generators or as
pulse-width modulators. Each timer has a single signal that can function as a GPIO signal or as a
timer signal. Each timer can also function as an event counter to capture an event or to measure
the width or period of a signal.
9.1 Overview
The timer module contains a common 21-bit prescaler and three independent and identical
general-purpose 24-bit timer/event counters, each with its own register set. Each timer has the
following capabilities:

9.1.1 Triple Timer Module Block Diagram
Figure 9-1 shows a block diagram of the triple timer module. This module includes a 24-bit
Timer Prescaler Load Register (TPLR), a 24-bit Timer Prescaler Count Register (TPCR), and
three timers. Each timer can use the prescaler clock as its clock source.

TIO
Uses internal or external clocking
Interrupts the DSP56309 after a specified number of events (clocks) or signals an external
device after counting internal events
Triggers DMA transfers after a specified number of events (clocks) occurs
Connects to the external world through one bidirectional signal, designated
TIO[0– 2]
is configured as an input, the timer functions as an external event counter or measures
for timers 0–2.
