(3) Character Size
The size of characters to be displayed can be selected from three
sizes for each block. Use the character size register (address
00E416) to set a character size. The character size in block 1 can be
specified by using bits 0 and 1 in the character size register ; the
character size in block 2 can be specified by using bits 2 and 3. Fig-
ure 25 shows the structure of the character size register.
The character size can be selected from three sizes : small size, me-
dium size and large size. Each character size is determined by the
number of scanning lines in the height (vertical) direction and the
cycle of display oscillation ( = Tc) in the width (horizontal) direction.
The small size consists of [one scanning line] ! [1 Tc] ; the medium
size consists of [two scanning lines] ! [2 Tc] ; and the large size con-
sists of [three scanning lines] ! [3 Tc].
Table 5 shows the relationship between the set values in the charac-
ter size register and the character sizes.

Fig. 25 Structure of character size register
Note : The display start position in the horizontal direction is not affected by the character size. In other words, the horizontal display start position is common to
all blocks even when the character size varies with each block (refer to Figure 26).
