(3) Character Size
The size of characters to be displayed can be from 4 sizes for each
block. Use the character size register (address 00E4
16
) to set a char-
acter size. The character size of block 1 can be specified by using
bits 0 and 1 of the character size register; the character size of block
2 can be specified by using bits 2 and 3; the character size of block 3
can be specified by using bits 4 and 5. Figure 51 shows the character
size register.
The character size can be selected from 4 sizes: minimum size, me-
dium size, large size and extra large size. Each character size is
determined by the number of scanning lines in the height (vertical)
direction and the oscillating cycle for display (T
C
) in the width (hori-
zontal) direction. The minimum size consists of [1 scanning line]
[1T
C
]; the medium size consists of [2 scanning lines]
[2T
C
]; the
large size consists of [3 scanning lines]
[3T
C
]; and the extra large
size consists of [4 scanning lines]
[4T
C
]. Table 7 shows the relation
between the set values in the character size register and the charac-
ter sizes.
