Clock waveform
Turn IC103 on.
Make sure IC103 is turned on.
Turn IC102 on.
IC103 generates 24.576 MHz from this clock
(14.725MHz) for 38-pin out.
IC103 outputs a verification signal for the
clock receiving.
Set each IC to WS mode.
IC101 inputs a verification signal that IC102 has
been in WS mode.
IC102 responds that TSCC data has been
received in WS mode.
Microcomputer reads out the received TSCC
data from IC102.
