ATmega8A

reference is kept on in sleep mode, the output can be used immediately. Refer to “Internal Volt-

age Reference” on page 40 for details on the start-up time.

9.7.5

Watchdog Timer

If the Watchdog Timer is not needed in the application, this module should be turned off. If the

Watchdog Timer is enabled, it will be enabled in all sleep modes, and hence, always consume

power. In the deeper sleep modes, this will contribute significantly to the total current consump-

tion. Refer to “Watchdog Timer” on page 41 for details on how to configure the Watchdog Timer.

9.7.6

Port Pins

When entering a sleep mode, all port pins should be configured to use minimum power. The

most important thing is then to ensure that no pins drive resistive loads. In sleep modes where

the both the I/O clock (clk

I/O) and the ADC clock (clkADC) are stopped, the input buffers of the

device will be disabled. This ensures that no power is consumed by the input logic when not

needed. In some cases, the input logic is needed for detecting wake-up conditions, and it will

then be enabled. Refer to the section “Digital Input Enable and Sleep Modes” on page 54 for

details on which pins are enabled. If the input buffer is enabled and the input signal is left floating

or have an analog signal level close to V

CC/2, the input buffer will use excessive power.
