7.5 Arithmetic/Logic Unit (ALU)
7.6 CPU During Break Interrupts
MC68HC708AS48
MOTOROLA
—
Rev. 4.0
The ALU performs the arithmetic and logic operations defined by the
instruction set.
Refer to the CPU08 Reference Manual (Motorola document 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.
