Compact Type TM

Although the simplest form of the three TM types, the Compact TM type still contains three operating modes, which are

Compare Match Output, Timer/Event Counter and PWM Output modes. The Compact TM can also be controlled with

an external input pin and can drive one or two external output pins. These two external output pins can be the same sig-

nal or the inverse signal.
