MITSUBISHI MICROCOMPUTERS
The display position in the vertical direction is determined by count-
ing the horizontal sync signal (HSYNC). At this time, when VSYNC and
HSYNC are positive polarity (negative polarity), it starts to count the
rising edge (falling edge) of HSYNC signal from after fixed cycle of
rising edge (falling edge) of VSYNC signal. So interval from rising edge
(falling edge) of VSYNC signal to rising edge (falling edge) of HSYNC
signal needs enough time (2 machine cycles or more) for avoiding
jitter. The polarity of HSYNC and VSYNC signals can select with the
I/O polarity control register (address 021716).

When bits 0 and 1 of the I/O polarity control register
(address 021716) are set to “1” (negative polarity)

Notes 1 : The vertical position is determined by counting falling edge of
HSYNC 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 VSYNC control signal in microcomputer to avoid jitter.
3 : The pulse width of VSYNC and HSYNC needs 8 machine cycles
or more.
