2.3
− The contents of the 3-Kbyte RAM area are undefined at system reset. Initialize this area by software.
− The contents of Segment 0 of the program memory space is read from the ROM reference area of Segment 8.
2.4
2.5
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).
