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. Below are two macros and an
enumerated type that can be used to interface to the Clock Prescale Register.

without a Clock Prescale Register, these macros are not available.
