Notes 1.
The cycle time (minimum instruction
execution time) of the CPU clock (
F
)
is determined by the oscillation
frequency of the connected resonator
(and external clock), the system clock
control register (SCC) and the
processor clock control register
(PCC). The figure at the right
indicates the cycle time t
