Timer Module
The triple timer module is composed of a common 21-bit prescaler and three independent and
identical general-purpose 24-bit timer/event counters, each with its own memory-mapped
register set. Each timer has the following properties:
A single signal that can function as a GPIO signal or as a timer signal
Uses internal or external clocking and can interrupt the DSP after a specified number
of events (clocks) or signal an external device after counting internal events
Connection to the external world through one bidirectional signal. When this signal is
configured as an input, the timer functions as an external event counter or measures
external pulse width/signal period. When the signal is used as an output, the timer
functions as either a timer, a watchdog, or a pulse width modulator.
