Note 4-4-1: These specifications are theoretical values. Add margin depending on its use.
Note 4-4-2: When starting transmission/reception of SIO7(SIO8) using serial-clock-input, a time from
SI7RUN(SI8RUN) being set when serial clock is "H" to the first negative edge of the serial clock must be
longer than 1tCYC.
