MC68HC908AS60 — Rev. 1.0
MOTOROLA
The ALU performs the arithmetic and logic operations defined by the
instruction set.
Refer to the CPU08 Reference Manual (Motorola document order
number CPU08RM/AD) for a description of the instructions and
addressing modes and more detail about CPU architecture.
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The WAIT instruction:
The STOP instruction:
After exiting stop mode, the CPU clock begins running after the oscillator
stabilization delay.

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.
