Timecode is available on 2 pins of the module. Pin 39 supplies 1.8V logic signal for internal use. Pin 16
gives the option to gradually reduce the level from 3V TTL down to mic level to adapt the signal to
different requirements. This signal can directly be used to jam sync with external equipment without
additional circuitry.
