12.2 Introduction
The MC68HC705P6A has an 8-K memory map. Therefore, it uses only
the lower 13 bits of the address bus. In the following discussion, the
upper three bits of the address bus can be ignored. Also, the STOP
instruction can be modified to place the MCU in either the normal stop
mode or the halt mode by means of a MOR bit. All other instructions and
registers behave as described in this section.
12.3 Registers
The MCU contains five registers which are hard-wired within the CPU
and are not part of the memory map. These five registers are shown in
Figure 12-1
and are described in the following paragraphs.
