43
44Many AVRs contain a Power Reduction Register (PRR) or Registers (PRRx) that
45allow you to reduce power consumption by disabling or enabling various on-board
46peripherals as needed. Some devices have the XTAL Divide Control Register
47(XDIV) which offer similar functionality as System Clock Prescale
48Register (CLKPR).
49
50There are many macros in this header file that provide an easy interface
51to enable or disable on-board peripherals to reduce power. See the table below.
52
53\note Not all AVR devices have a Power Reduction Register (for example
54the ATmega8). On those devices without a Power Reduction Register, the
55power reduction macros are not available..
56
57\note Not all AVR devices contain the same peripherals (for example, the LCD
58interface), or they will be named differently (for example, USART and
59USART0). Please consult your device's datasheet, or the header file, to
60find out which macros are applicable to your device.
61
62\note For device using the XTAL Divide Control Register (XDIV), when prescaler
63is used, Timer/Counter0 can only be used in asynchronous mode. Keep in mind
64that Timer/Counter0 source shall be less than ¼th of peripheral clock.
65Therefore, when using a typical 32.768 kHz crystal, one shall not scale
66the clock below 131.072 kHz.

1399/** \addtogroup avr_power
1400
1401Some of the newer AVRs contain a System Clock Prescale Register (CLKPR) that
1402allows you to decrease the system clock frequency and the power consumption
1403when the need for processing power is low.
1404On some earlier AVRs (ATmega103, ATmega64, ATmega128), similar
1405functionality can be achieved through the XTAL Divide Control Register.
1406Below are two macros and an enumerated type that can be used to
1407interface to the Clock Prescale Register or
1408XTAL Divide Control Register.
1409
1410\note Not all AVR devices have a clock prescaler. On those devices
1411without a Clock Prescale Register or XTAL Divide Control Register, these
1412macros are not available.
