nificantly to the total current consumption. Refer to
on how to configure the Brown-out Detector.
The Internal Voltage Reference will be enabled when needed by the Brown-out Detection or the
Analog Comparator. If these modules are disabled as described in the sections above, the inter-
nal voltage reference will be disabled and it will not be consuming power. When turned on again,
the user must allow the reference to start up before the output is used. If the reference is kept on
in sleep mode, the output can be used immediately. Refer to
page 38
If the Watchdog Timer is not needed in the application, the 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
When entering a sleep mode, all port pins should be configured to use minimum power. The
most important is then to ensure that no pins drive resistive loads. In sleep modes where the I/O
clock (clk

for detecting wake-up conditions, and it will then be enabled. Refer to the section

For analog input pins, the digital input buffer should be disabled at all times. An analog signal
level close to V
input buffers can be disabled by writing to the Digital Input Disable Registers (DIDR). Refer to
