H-COUNTER SYNCHRONIZATION
The H-Counter reset occurs seven CLI cycles following the HD
falling edge. The PxGA steering is synchronized with the reset
of the internal H-Counter (see Figure 13).

NOTES
1. INTERNAL H-COUNTER IS RESET SEVEN CLI CYCLES AFTER THE HD FALLING EDGE (WHEN USING VDHDEDGE = 0).
2. TYPICAL TIMING RELATIONSHIP: CLI RISING EDGE COINCIDES WITH HD FALLING EDGE.
3. PxGA STEERING IS SYNCHRONIZED WITH THE RESET OF THE INTERNAL H-COUNTER (MOSAIC SEPARATE MODE IS SHOWN).
