/** \defgroup avr_power <avr/power.h>: Power Reduction Management

\code #include <avr/power.h>\endcode

Many AVRs contain a Power Reduction Register (PRR) or Registers (PRRx) that 
allow you to reduce power consumption by disabling or enabling various on-board 
peripherals as needed. Some devices have the XTAL Divide Control Register
(XDIV) which offer similar functionality as System Clock Prescale
Register (CLKPR).

There are many macros in this header file that provide an easy interface
to enable or disable on-board peripherals to reduce power. See the table below.

\note Not all AVR devices have a Power Reduction Register (for example
the ATmega8). On those devices without a Power Reduction Register, the
power reduction macros are not available..

\note Not all AVR devices contain the same peripherals (for example, the LCD
interface), or they will be named differently (for example, USART and 
USART0). Please consult your device's datasheet, or the header file, to 
find out which macros are applicable to your device.

\note For device using the XTAL Divide Control Register (XDIV), when prescaler
is used, Timer/Counter0 can only be used in asynchronous mode. Keep in mind
that Timer/Counter0 source shall be less than ¼th of peripheral clock.
Therefore, when using a typical 32.768 kHz crystal, one shall not scale
the clock below 131.072 kHz.

/** \addtogroup avr_power

Some of the newer AVRs contain a System Clock Prescale Register (CLKPR) that
allows you to decrease the system clock frequency and the power consumption
when the need for processing power is low.
On some earlier AVRs (ATmega103, ATmega64, ATmega128), similar
functionality can be achieved through the XTAL Divide Control Register.
Below are two macros and an enumerated type that can be used to
interface to the Clock Prescale Register or
XTAL Divide Control Register.

\note Not all AVR devices have a clock prescaler. On those devices
without a Clock Prescale Register or XTAL Divide Control Register, these
macros are not available.

        //    read-modify-write since we will rewrite XDIV later anyway)

        //5 - Set XDIVEN bit in calculated value
