7.7 Instruction Set Summary
Technical Data
88
The arithmetic/logic unit (ALU) performs the arithmetic and logic
operations defined by the instruction set.
Refer to the CPU08 Reference Manual, Freescale document order
number CPU08RM/AD, for a description of the instructions and
addressing modes and more detail about CPU architecture.
If the break module is enabled, a break interrupt causes the CPU to
execute the software interrupt instruction (SWI) at the completion of the
current CPU instruction. See
program counter vectors to $FFFC–$FFFD ($FEFC–$FEFD in monitor
mode).
A return-from-interrupt instruction (RTI) in the break routine ends the
break interrupt and returns the MCU to normal operation if the break
interrupt has been deasserted.
Table 7-1
provides a summary of the M68HC08 instruction set.
