CPU Control Unit
The CPU control unit fetches and decodes instructions during program
operation. The control unit selects the memory locations to read and
write and coordinates the timing of all CPU operations.
Arithmetic/Logic Unit
The arithmetic/logic unit (ALU) performs the arithmetic, logic, and
manipulation operations decoded from the instruction set by the CPU
control unit. The ALU produces the results called for by the program and
sets or clears status and control bits in the condition code register
(CCR).
CPU Registers
The M68HC05 CPU contains five registers that control and monitor MCU
operation:
Accumulator
Index register
Stack pointer
Program counter
Condition code register
CPU registers are not memory mapped.
