CPU clock cycle time
(Instruction execution time)
INT high-/low-level width
RESET low-level width
Note
The CPU clock cycle time (instruction execution time) is determined by the oscillation frequency of the
resonator connected and SYSCK (RF: address 02H) of the register file. The figure below shows the CPU
