Notes 1.
The cycle time of the CPU clock (
f
) (minimum instruction execution time) when the device operates with
the main system clock is determined by the time constant of the connected resistor (R) and capacitor
(C), and the value of the processor clock control register (PCC). When the device operates with the
subsystem clock, the cycle time of the CPU clock (
f
) is determined by the oscillation frequency of the
connected oscillator (and external clock), and the values of the system clock control register (SCC) and
processor clock control register (PCC).
