PROGRAM MEMORY (ROM)
The program memory is a mask ROM. 1 word of ROM is
composed of 9 bits. ROM is separated every 128 words by the
unit of page (addresses 0 to 127).
Table 1 ROM size and pages
Fig. 11 RAM map
Page 2 (addresses 010016 to 017F16) is the special page for
subroutine calls. Subroutines written in this page can be called
from any page with the 1-word instruction (BM). Subroutines
extending from page 2 to another page can also be called with
the BM instruction when it starts on page 2.
ROM pattern of all addresses can be used as data areas with
the TABP p instruction.
DATA MEMORY (RAM)
1 word of RAM is composed of 4 bits, but 1-bit manipulation
(with the SB j, RB j, and SZB j instructions) is enabled for the
entire memory area. A RAM address is specified by a data
pointer. The data pointer consists of registers X and Y. Set a
value to the data pointer certainly when executing an instruction
to access RAM.
Table 2 shows the RAM size. Figure 12 shows the RAM map.
