● RAM Interface
The external RAM is used to store display data (text, graphic and external CG data).
With single−scan, text data, graphic data and external CG data can be freely allocated to the memory area
(64 KB max).
With dual−scan, LCD I is allocated to 0000H to 7FFFH (32 KB max), LCD II is allocated to 8000H to FFFFH
(32 KB max). Text data, graphic data and external CG data can be freely allocated in LCD I. In LCDII, the
same addresses must be allocated as in LCD I, except ad15. ad15 determines selection of LCD I or LCD II.
It can be use the address decoded signals ce0 (0000 to 07FFH), ce1 (0800 to 0FFFH) within 4 KB.
ce0 and ce1 allow decoding of addresses in the ranges (0000 to 07FFH) and (0800 to 0FFFH) respectively
within a 4−KB memory space.
