(2) Display Position
The display positions of characters are specified in units called a
“block.” There are 2 blocks, block 1 and block 2. Up to 24 characters
can be displayed in each block (refer to (4) Memory for Display).
The display position of each block can be set in both horizontal and
vertical directions by software.
The display position in the horizontal direction can be selected for all
blocks in common from 64-step display positions in units of 4T
C
(T
C
= oscillating cycle for display).
The display position in the vertical direction for each block can be
selected from 128-step display positions in units of 4 scanning lines.
Block 2 is displayed after the display of block 1 is completed (refer to
Figure 34 (a)). Accordingly, if the display of block 2 starts during the
display of block 1, only block 1 is displayed. Similarly, when multiline
display, block 1 is displayed after the display of block 2 is completed
(refer to Figure 34 (b)).
The vertical position can be specified from 128-step positions (4 scan-
ning lines per a step) for each block by setting values “00
16
” to “7F
16
”
to bits 0 to 6 in the vertical position register (addresses 00E1
16
and
00E2
16
). Figure 36 shows the structure of the vertical position regis-
ter.
