SECTION 3
CENTRAL PROCESSING UNIT
The MC68HC05PD6 has a 64 kbytes memory map. 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 ve registers which are hard-wired within the CPU and are not
part of the memory map. These ve registers are shown in Figure 3-1 and are
described in the following paragraphs.
