= 2.0 to 6.0 V)
Notes 1.
The cycle time of the CPU clock (
Φ
)
depends on the connected resonator
frequency, the system clock control reg-
ister (SCC), and the processor clock
control register (PCC).
The figure on the right side shows the
cycle time t

characteristics for the supply
voltage V

during main system clock
operation.

This value becomes 2t

ac-
cording to the setting of the interrupt
mode register (IM0).
