Functional Description
The external inputs to each counter/timer are shareable among each of the four counter/
timers within the module. The external inputs can be used as:
The polarity of the external inputs are selectable.
The primary output of each timer/counter is the output signal OFLAG. The OFLAG
output signal can be:
Any counter/timer can be assigned as a master. A master's compare signal can be
broadcast to the other counter/timers within the module. The other counters can be
configured to reinitialize their counters and/or force their OFLAG output signals to
predetermined values when a master's counter/timer compare event occurs.

• The counter can count up and down using dual inputs in a "count with direction"
• The counter's terminal count value (modulo) is programmable.
• The counter can count repeatedly, or it can stop after completing one count cycle.
• The counter can be programmed to count to a programmed value and then
• Count commands
• Timer commands
• They can trigger the current counter value to be "captured"
• They can be used to generate interrupt requests
• Set, cleared, or toggled when the counter reaches the programmed value.
• The OFLAG output signal may be output to an external pin instead of having that pin
• The OFLAG output signal enables each counter to generate square waves, PWM, or
• The polarity of the OFLAG output signal is selectable.

pulse stream outputs.
• The value that is loaded into the counter after reaching its terminal count is
programmable.
