Character Generator RAM (CGRAM)
The S1D12400 series is provided with a CGROM that permits the user to program character patterns so as to attain a
character display with a high degree of freedom. When using the CGRAM, select Use of CGRAM by the system set
command. The CGRAM capacity is 240 bits having a structure of 5 × 8 dots and optional 6 types of patterns can be
registered.
The relation among CGRAM character patterns, CGRAM addresses, and character codes is shown below.
The character size of 5 × 8 can also be set. In this case, use the RAM of *7H, *FH of the CGRAM address. However,
when the under-bar cursor is used, the data of *7H, *FH is displayed in reverse form.
