    Bits 3..0 – CLKPS3..0: Clock Prescaler Select Bits 3 - 0
    These bits define the division factor between the selected clock source and the internal system
    clock. These bits can be written run-time to vary the clock frequency to suit the application
    requirements. As the divider divides the master clock input to the MCU, the speed of all synchro-
    nous peripherals is reduced when a division factor is used. The division factors are given in
    The CKDIV8 Fuse determines the initial value of the CLKPS bits. If CKDIV8 is unprogrammed,
    the CLKPS bits will be reset to “0000”. If CKDIV8 is programmed, CLKPS bits are reset to
    “0011”, giving a division factor of 8 at start up. This feature should be used if the selected clock
    source has a higher frequency than the maximum frequency of the device at the present operat-
    ing conditions. Note that any value can be written to the CLKPS bits regardless of the CKDIV8
    Fuse setting. The Application software must ensure that a sufficient division factor is chosen if
    the selcted clock source has a higher frequency than the maximum frequency of the device at
    the present operating conditions. The device is shipped with the CKDIV8 Fuse programmed.
