(12) Synchronizing Signal Counter
The synchronizing signal counter counts the composite sync signal
taken out from a video signal in the data slicer circuit or the vertical
synchronizing signal Vsep as a count source.
The count value in a certain time (T time) generated by f(XIN)/213 or
f(XIN)/213 is stored into the 5-bit latch. Accordingly, the latch value
changes in the cycle of T time. When the count value exceeds “1F16,”
“1F16” is stored into the latch.
The latch value can be obtained by reading out the sync pulse counter
register (address 00EA16). A count source is selected by bit 5 of the
sync pulse counter register.
The synchronizing signal counter is used when bit 0 of the PWM
mode register 1 (address 02EA16).
Figure 34 shows the structure of the sync pulse counter and Figure
35 shows the synchronizing signal counter block diagram.
