GENERAL RELEASE SPECIFICATION
PRELIMINARY
will be output to the HSYNO and VSYNO pins. When it is one,
the free-running 55.556KHz HSYNC with 2us negative pulse
and 72.34Hz VSYNC with 108us negative pulse will be
generated to the HSYNO and VSYNO output stages. Reset
clears this bit.

Vertical Frequency Registers (VFRs)
This 13-bit read only register pair contains information of the vertical frame frequency. An
internal counter counts the number of internal clocks between two VSYNC pulses. The
most significant 5 bits of counted value will then be transferred to high byte register, $0D,
and the least significant 8 bits of counted value is transferred to one intermediate buffer.
When the high byte register is read, the 8-bit counted value stored in the intermediate buffer
will be uploaded to the low byte register, $0E. So the program must read the high byte
register first then low byte register in order to get the complete counted value of one vertical
frame. If the counter overflow, the VOF flag will be set while the counter values stored in
