1.
The CPU clock (
Φ
) cycle time (minimum
instruction execution time) is determined by
the oscillatior frequency of the connected
resonator, the system clock control register
(SCC) and the processor clock control register
(PCC). The figure at the right indicates the
cycle time t
CY
versus supply voltage V
DD
characteristic with the main system clock
operating.
