6. Pulse output

The bits of the remote control word, as indicated by the addressed ROM locations, are loaded into a shift

register every bit-time this register is shifted. The output is used to generate a logic1 in the biphase (Manchester)

coding, modulated with a frequency of 36 KHz. The duty factor of the modulation pulses may be selected

(optionally) to be 25% or 33.3%. The output of the pulse generator controls the output driver that can provide a

maximum current of 5 mA.
