The display start position in the vertical direction is determined by
counting the horizontal sync signal (H
SYNC
). At this time, when V
SYNC
and H
SYNC
are positive polarity (negative polarity), it starts to count
the rising edge (falling edge) of H
SYNC
signal from after fixed cycle of
rising edge (falling edge) of V
SYNC
signal. So interval from rising edge
(falling edge) of V
SYNC
signal to rising edge (falling edge) of H
SYNC
signal needs enough time (2 machine cycles or more) for avoiding
jitter. The polarity of H
SYNC
and V
SYNC
signals can select with the
I/O polarity control register (address 0217
16
).

Notes 1 :
The vertical position is determined by counting falling edge of
H
SYNC
signal after rising edge of V
SYNC
control signal in the
microcomputer.
2 :
Do not generate falling edge of H
SYNC
signal near rising edge
of V
SYNC
control signal in microcomputer to avoid jitter.
3 :
The pulse width of V
SYNC
and H
SYNC
needs 8 machine cycles
or more.
