Preliminary
ADDRESSING
Display RAM Structure
Whereas ‘Figure 9. Memory Map of Display Registers’showed a logical configuration, the Figure above shows a
1KByte SRAM (512
×
16 bit)'s practical and physical configuration. For facilitating internal calculations, addressing
is done using exponents of 2, and the rows to the right of the 'Row Attribute Registers', excepting only IFF(255),
are 'Virtual Registers' that are not used.
If you set 'Frame Control Register 0's 'Erase' bit to '1', 480 areas are erased (excepting only the 16th line) in the
Figure above, and the 'Erasing Time' is measured with 480 areas as the standard.
