• Description: 16-Bit CMOS Microcontroller
• Manufacturer: Infineon Technologies

In Center Aligned Mode the compare timer T12 counts up starting at 0000
reaching the period value stored in register T12P the count direction is reversed and the
timer counts down. The output signals are switched to their active/passive state upon a
match with the compare value while counting up/down. Center aligned mode is
supported by compare timer T12 only.
The compare timers T12 and T13 are free running timers which are clocked with a
programmable frequency of
The respective output signals are changed (if appropriate) when the timer reaches the
programmed compare value. For switching the output signals COUT60 … COUT62 the
contents of the timer plus the offset value are compared against the compare value.
Timer T12 can operate in either edge aligned or center aligned PWM mode (see
Figure
Timer T13 can operate in edge aligned mode without edge delay.
