Fig. 8.10.12 Sync Pulse Counter Register
8.10.13 Synchronous Signal Counter
The synchronous signal counter counts the composite sync signal
taken out from a video signal in the data slicer circuit or the vertical
synchronous 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.
Fig. 8.10.13 Synchronous Signal Counter Block Diagram
The latch value can be obtained by reading out the sync pulse counter
register (address 00E916). A count source is selected by bit 5 of the
sync pulse counter register.
The synchronous signal counter is used when bit 0 of PWM mode
register 1 (address 020816).
Figure 8.10.12 shows the structure of the sync pulse counter and
Figure 8.10.13 shows the synchronous signal counter block diagram.
