GENERAL RELEASE SPECIFICATION
PRELIMINARY
SECTION 3
CPU CORE
The MC68HC05BD7 has a 16K memory map. Therefore it uses only the lower 14 bits of
the address bus. In the following discussion the upper 2 bits of the address bus can be
ignored. The stack has only 64 bytes. Therefore, the stack pointer has been reduced to only
6 bits and will only decrement down to $00C0 and then wrap-around to $00FF. All other
instructions and registers behave as described in this chapter.
3.1
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 3-1 and are described in the
following paragraphs.

3.1.1
Accumulator (A)
The accumulator is a general purpose 8-bit register as shown in Figure 3-1. The CPU uses
the accumulator to hold operands and results of arithmetic calculations or non-arithmetic
operations. The accumulator is not affected by a reset of the device.
