6.5.3 Data-Retention Mode

Rev. 1.0
Refer to
additional information.
The WAIT instruction places the MCU in a low power-consumption
mode, but the wait mode consumes more power than the stop mode. All
CPU action is suspended, but the timer, CPI, COP, SSI, and M bus
remain active. An interrupt from the timer, SSI, or M bus can cause the
MCU to exit the wait mode.
During the wait mode, the I bit in the CCR is cleared to enable interrupts.
All other registers, memory, and input/output lines remain in their
previous state. The timer, SSI, and/or IIC modules may be enabled to
allow a periodic exit from the wait mode.
Refer to
additional information.
The contents of RAM and CPU registers are retained at supply voltages
as low as 2.0 Vdc. This is called the data-retention mode where the data
is held, but the device is not guaranteed to operate. RESET must be held
low during data-retention mode.
