Note
The CPU clock cycle time (instruction execution time)
is determined by the oscillation frequency of the reso-
nator connected and SYSCK (RF: address 02H) of the
register file.
The figure on the right shows the CPU clock cycle time
tCY vs. supply voltage VDD characteristics (refer to 4.
CLOCK GENERATOR CIRCUIT).
