(4) Timing Signal Generating Circuit
This circuit generates a reference clock which is 832 times as large
as the horizontal synchronizing signal frequency. It also generates
various timing signals on the basis of the reference clock, horizontal
synchronizing signal and vertical synchronizing signal. The circuit
operates by setting bit 0 of data slicer control register 2 (address
00EB16) to “1.”
The reference clock can be used as a display clock for OSD function
in addition to the data slicer. The HSYNC signal can be used as a
count source instead of the composite sync signal. However, when
the HSYNC signal is selected, the data slicer cannot be used. A count
source of the reference clock can be selected by bit 1 of data slicer
control register 2 (address 00EB16).
