Notes : • tHCYL is the oscillation cycle for the internal main clock.
• If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause
malfunctions. Use caution so that the reset pulse less than the specifications will not be fed to the external
reset pin (RST).
