CLK
There is an internal PLL that provides nominally 64 MHz clock rate locked to the RC Oscillator
for the use of the Peripheral Timer/Counter1 and for the system clock source. When selected as
a system clock source, by programming (“0”) the fuse PLLCK, it is divided by four. When this
option is used, the CKSEL3..0 must be set to “0001”. This clocking option can be used only
when operating between 4.5 - 5.5V to guaratee safe operation. The system clock frequency will
be 16 MHz (64 MHz/4). When using this clock option, start-up times are determined by the SUT
Fuses as shown in Table 15. See also “PCK Clocking System” on page 24.
