The UTCM consists of one timer (Timer 2) and a serial interface. There is a multitude of modes
in which the timers and serial interface can work together. The 8-bit wide serial interface oper-
ates as shift register for modulation. The modulator units work together with the timers and shift
the data bits into or out of the shift register.
