3.1 Contents
3.2 Introduction
This section describes the registers of the M68HC05 central processor
unit (CPU). The stop and wait modes, initiated by software instructions,
are also described here.
3.3 CPU Registers
The CPU contains the following registers:
Accumulator (A)
Index register (X)
Stack pointer (SP)
Program counter (PC)
Condition code register (CCR)
These registers are hard-wired within the CPU and are not part of the
memory map. Figure 3-1 is a block diagram of the M68HC05 CPU.
