Technical Manual
9.2. Screen Configuration
9.2.1. Screen configuration
The basic screen configuration of the S1D13305 series is
as a single text screen or as overlapping text and graphics
screens. The graphics screen uses eight times as much
display memory as the text screen.
Figure 28 shows the relationship between the virtual
screens and the physical screen.
9.2.2. Display address scanning
The S1D13305 series scans the display memory in the
same way as a raster scan CRT screen. Each row is
scanned from left to right until the address range equals
C/R. Rows are scanned from top to bottom.
In graphics mode, at the start of each line, the address
counter is set to the address at the start of the previous line
plus the address pitch, AP.
In text mode, the address counter is set to the same start
address, and the same character data is read, for each row
in the character bitmap. However, a new row of the
character generator output is used each time. Once all the
rows in the character bitmap have been displayed, the
address counter is set to the start address plus AP and the
next line of text is displayed.
