V
ERTICAL POSITION
The line number of the vertical start position for:
Row 0 is 4
×
(VP00
→
VP05)
Row 1 is 4
×
(VP10
→
VP15).
Where:
(VP00
→
VP05) = the decimal value of VP00
→
VP05
(VP10
→
VP15) = the decimal value of VP10
→
VP15.
The character height in:
Row 0 is H0 and is a function of the number of dots per
character and the state of the size control bits
SZ00 and SZ01
Row 1 is H1 and is a function of the number of dots per
character and the state of the size control bits
SZ10 and SZ11.
Row 0 and Row 1 must not overlap each other and
therefore: VP1
≥
(VP0 + H0); see Fig.25.
The four possible character heights are shown in Table 23.

ORIZONTAL POSITION
The horizontal start position (HP) of,
Row 0: HP0 = 4

Where:
(HP00

HP05
and (HP00

HP05) > 10
(HP10

HP15
and (HP10
