Parameter
2.
The cycle time (minimum instruction
execution time) of the CPU clock
( ) 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
versus
characteristic with the main system
clock operating.
