Incoming LTC data is loaded into the receive buffer following the receipt of a valid LTC SYNC pattern.
* SMPTE SYNC Sources -
A time code generator must have a SYNC input from a stable source in
order to position the LTC code properly on an audio track of video tape or film. Two SYNC sources, click
input, and free running, are available. If some external SYNC source is available it can be input on the
CLICK input. Otherwise, a free running SMPTE SYNC is generated from the oscillator at the selected
frame rate.
