Low Power Modes
6.3 Wait Mode
Technical Data
78
The WAIT instruction puts the MCU in an intermediate power-
consumption mode and has the following effects on the MCU:
The WAIT instruction does not affect any other registers or any I/O lines.
The following conditions restart the CPU clock and bring the MCU out of
wait mode:

For More Information On This Product,
Clears the I bit in the condition code register, enabling interrupts
Stops the CPU clock, but allows the internal clock to drive the
capture/compare timer, the COP watchdog, and the ADC
External interrupt — A high-to-low transition on the IRQ/V
loads the program counter with the contents of locations $1FFA
and $1FFB.
Timer interrupt — Input capture, output compare, and timer
overflow interrupt requests load the program counter with the
contents of locations $1FF8 and $1FF9.
COP watchdog reset — A timeout of the COP watchdog resets the
MCU and loads the program counter with the contents of locations
$1FFE and $1FFF. Software can enable timer interrupts so that
the MCU can periodically exit wait mode to reset the COP
watchdog.
External reset — A logic zero on the RESET pin resets the MCU
and loads the program counter with the contents of locations
$1FFE and $1FFF.
