The UTCM consists of two timers (Timer 2 and Timer 3) 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 operates as shift register for modulation and demodula-
tion. The modulator and demodulator units work together with the timers and shift the
data bits into or out of the shift register.
