and loads content into the receive buffer when complete telegram has been received.
The UTCM consists of two timers (Timer 2 and Timer 3) and a serial interface. There is a multi-
tude 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 demodulation. The
modulator and demodulator units work together with the timers and shift the data bits into or out
of the shift register.
