Data Sheet
The figure below shows an example for the generation of a PWM signal using the
alternate reload mechanism. T2 defines the high time of the PWM signal (reloaded on
positive transitions) and T4 defines the low time of the PWM signal (reloaded on negative
transitions). The PWM signal can be output on line T3OUT if the control bit T3OE is set
to ‘1’. With this method the high and low time of the PWM signal can be varied in a wide
range.
Note:
1. The output toggle latch T3OTL is accessible via software and may be changed, if
2. An associated port pin linked to line T3OUT should be configured as output.

Note: Although it is possible, it should be avoided to select the same reload trigger event
required, to modify the PWM signal. However, this will NOT trigger the reloading of T3.
Note: Lines ’*’ only affected by over/underflows of T3, but NOT by software

for both auxiliary timers. In this 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.
