The data memory space of this LSI consists of the ROM window area, 3KByte RAM area and SFR area of Segment 0
and the ROM reference areas of Segment 8.
The data memory stores 8-bit data and is specified by 20 bits consisting of higher 4 bits as DSR and lower 16 bits as
addressing specified by each instruction.
Figure 2-2 shows the configuration of the data memory space.
Notes:
The length of a instruction is 16 bits.
The data types supported include byte (8 bits) and word (16 bits).
