Table 5-5.
The Universal Timer/counter/Communication Module (UTCM) consists of three timers
(Timer 1,Timer 2, Timer 3) and a Synchronous Serial Interface (SSI).
There is a multitude of modes in which the timers and the serial interface can work together.
P6DAT
P6CR
• Timer 1 is an interval timer that can be used to generate periodic interrupts and as prescaler
• 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 a 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.
