PROGRAM MEMORY (ROM)
1 word of ROM is composed of 10 bits. ROM is separated every
128 words by the unit of page (addresses 0 to 127). Table 1
shows the ROM size and pages. Figure 10 shows the ROM map
of M34551E8.

A top part of page 1 (addresses 008016 to 00FF16) is reserved
for interrupt addresses (Figure 11). When an interrupt occurs,
the address (interrupt address) corresponding to each interrupt
is set in the program counter, and the instruction at the interrupt
address is executed. When using an interrupt service routine,
write the instruction generating the branch to that routine at an
interrupt address.
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 (bits 7 to 0) of all addresses can be used as data
areas with the TABP p instruction.
