Sets SP bar width on the basis of parameter m, setting by
parameter S (MSB valid).
S ADJUSTMENT VALUE FOR THE STANDARD
WIDTH OF SP BAR (1/360 IN UNIT)
FDH -3
FEH -2
FFH -1
00H 0 (default)
01H +1
02H +2
03H +3
For settings other than above, the value is set to 0.
Sets height (1/180 in unit) of black bar by parameter v1
and v2.
Black bar height = v1 + v2 x 256
0(00H) <= v1 <= 255(FFH)
0(00H) <= v2 <= 255(FFH)
The maximum setting value for height is 2 in. This can be
set in units of 15/180 in as follows:
SETTING RANGE
1 <= v1.v2 <= 15
16 <= v1.v2 <= 30
31 <= v1.v2 <= 45
46 <= v1.v2 <= 60
61 <= v1.v2 <= 75
76 <= v1.v2 <= 90
91 <= v1.v2 <= 105
106 <= v1.v2 <= 120
121 <= v1.v2 <= 135
