The Vsync is separated from the composite sync automatically, without any software effort.

the V

d. Horizontal & Vertical Frequency Counter
There are two 16-bit counters which can count H and V frequency automatically. When a VEVENT (V
frequency counter timeout) interrupt occurs, the MCU may read the count value (Hcount and Vcount)
from the counter registers (HFCOUNTH, HFCOUNTL, VFCOUNTH and VFCOUNTL) to calculate the
H and V frequency by the formulas listed below.
