M-3. Horizontal & Vertical Frequency Counter
There are two 16-bit counters that automatically count the horizontal and vertical frequency. When a
VEVENT interrupt occurs, the W78C354 reads the count value (H
COUNT
and V
COUNT
) from the 8-bit
counter registers (HFCOUNTH, HFCOUNTL, VFCOUNTH, and VFCOUNTL) to calculate the H and V
frequency by the formulas listed below.
