When the display dot line selection bit is
“
0,
”
the
“
”
font is displayed at even field, the
“
”
font is displayed at odd field. Bit 7 of the
I/O polarity control register can be read as the
field determination flag :
“
1
”
is read at odd field,
“
0
”
is read at even field.
Note :
The field determination flag changes at a rising edge of the V
SYNC
control signal (negative-polarity input) in
the microcomputer.
