Z — Zero Flag
C — Carry/Borrow Flag
6.4 Arithmetic/Logic Unit (ALU)
The ALU performs the arithmetic and logic operations defined by the instruction set.
Refer to the CPU08 Reference Manual (document order number CPU08RM/AD) for a description of the
instructions and addressing modes and more detail about the architecture of the CPU.
6.5 Low-Power Modes
The WAIT and STOP instructions put the MCU in low power-consumption standby modes.
6.5.1 Wait Mode
The WAIT instruction:
6.5.2 Stop Mode
The STOP instruction:
After exiting stop mode, the CPU clock begins running after the oscillator stabilization delay.
6.6 CPU During Break Interrupts
If a break module is present on the MCU, the CPU starts a break interrupt by:
The break interrupt begins after completion of the CPU instruction in progress. If the break address
register match occurs on the last cycle of a CPU instruction, the break interrupt begins immediately.
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.
Freescale Semiconductor
The CPU sets the zero flag when an arithmetic operation, logic operation, or data manipulation
produces a result of $00.
The CPU sets the carry/borrow flag when an addition operation produces a carry out of bit 7 of the
accumulator or when a subtraction operation requires a borrow. Some instructions — such as bit test
and branch, shift, and rotate — also clear or set the carry/borrow flag.

1 = Zero result
0 = Non-zero result
1 = Carry out of bit 7
0 = No carry out of bit 7
Clears the interrupt mask (I bit) in the condition code register, enabling interrupts. After exit from
wait mode by interrupt, the I bit remains clear. After exit by reset, the I bit is set.
Disables the CPU clock
Clears the interrupt mask (I bit) in the condition code register, enabling external interrupts. After
exit from stop mode by external interrupt, the I bit remains clear. After exit by reset, the I bit is set.
Disables the CPU clock
Loading the instruction register with the SWI instruction
Loading the program counter with $FFFC:$FFFD or with $FEFC:$FEFD in monitor mode
