(2) Display Position

The display positions of characters are specified in units called a

“block.” There are 3 blocks, blocks 1 to 3. 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 4TC

(TC = 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 46 (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 46 (b)).

The vertical position can be specified from 128-step positions (4 scan-

ning lines per a step) for each block by setting values “0016” to “7F16”

to bits 0 to 6 in the vertical position register (addresses 00E116 to

00E316). Figure 48 shows the vertical position register.
