Universal Timer/Counter/ Communication Module (UTCM)

The Universal Timer/counter/Communication Module (UTCM) consists of three timers

(Timer 1,Timer 2, Timer 3) and a Synchronous Serial Interface (SSI).

• Timer 1 is an interval timer that can be used to generate periodical interrupts and as

prescaler for Timer 2, Timer 3, the serial interface and the watchdog function.

• Timer 2 is an 8/12-bit timer with an external clock input (T2I) and an output (T2O).

• Timer 3 is an 8-bit timer/counter with its own input (T3I) and output (T3O).

• The SSI operates as two wire serial interface or as shift register for modulation and

demodulation. The modulator and demodulator units work together with the timers and shift

the data bits into or out of the shift register.

There is a multitude of modes in which the timers and the serial interface can work together.
