3.3 SYNC Processor
The sync processor contains the following functions: polarity detection, presence detection, H-Freq counter,
V-Freq counter and sync signal separation for input SYNC sources (HS and VS). It can be programmed to
change the detected polarity status and output polarity of SYNC pins (HBLANK and VBLANK) by using the
command interface. The timing diagrams of sync processing are shown as Fig. 2 in section 8.0. The internal
SYNC signals (Hsync and Vsync) are extracted from different sources according to the following modes of
operation.

3.4 H-Freq Table
After the "start H-Freq count" command is issued over 10 ms (for 15.7KHz) and HCFF(H-Freq Count Finished
Flag) is set
High,
the H-Freq output (HF9 - HF0) is valid. The output value of H-Freq is calculated using the
following formula:
output value = [(1/fHfreq(KHz)) x 64 x 4000] / 16

3.5 V-Freq Table
After the "start V-Freq count" command is issued over 120 ms (for 50HZ) and VCFF (V-Freq Count Finish Flag)
is set
High,
the V-Freq output (VF8 - VF0) is valid. The output value of V-Freq is calculated according to the
following formula:
output value = [(4/fVfreq(Hz)) x 4000000] / (64 x 16)
