The reload mode triggered by T3OTL can be used in a number of different
configurations. The following functions can be performed, depending on the selected
active transition:
• If both a positive and a negative transition of T3OTL are selected to trigger a reload,
• If either a positive or a negative transition of T3OTL is selected to trigger a reload, the
• Using this “single-transition” mode for both auxiliary timers allows very flexible Pulse
Note: Although possible, selecting the same reload trigger event for both auxiliary timers
User’s Manual
the core timer will be reloaded with the contents of the auxiliary timer each time it
overflows or underflows. This is the standard reload mode (reload on overflow/
underflow).
core timer will be reloaded with the contents of the auxiliary timer on every second

Width Modulation (PWM). One of the auxiliary timers is programmed to reload the
core timer on a positive transition of T3OTL, the other is programmed for a reload on
a negative transition of T3OTL. With this combination, the core timer is alternately
reloaded from the two auxiliary timers.
should be avoided. In such a case, both reload registers would try to load the core
timer at the same time. If this combination is selected, T2 is disregarded and the
contents of T4 is reloaded.
