Chapter 3: Architecture

Each timer can be used for internal or external clocking and
can interrupt the on-board DSP after a specified number of

events (clocks) or signal an external device after counting
internal events. Each timer can also be used to trigger DMA

transfers after a specified number of events (clocks) have
occurred. Each timer connects to the external world through

one bi-directional pin TIO that is 7kV ESD protected. When
TIO is configured as input the timer functions as an external

event counter or can measure external pulse width/signal
period. When TIO is used as output, it functions as a timer,

watchdog or Pulse Width Modulator.

Some common timer/counter/output functions that

microprocessors require are:
Real time clock,

Event counter
Digital one-shot

Programmable rate generator
Square wave generator

Binary rate multiplier
Complex digital wave form generator

Complex motor control

Note Each counter is a 24-bit count-up counter

After power-up, the count value and output of all counters

are set to zero

Each counter must be programmed before it can be used

Unused counters need not to be programmed

Use the PowerDAQ API to program counters.

Each counter is fully independent of the others. Only

prescaler, when used, is a common part of the counter-timer
subsystem. Each counter may operate in a different mode
