Note 4-1-1: These specifications are theoretical values. Add margin depending on its use.
Note 4-1-2: To use serial-clock-input in continuous trans/rec mode, a time from SI0RUN being set when serial clock is
"H" to the first negative edge of the serial clock must be longer than tSCKHA.
Note 4-1-3: Must be specified with respect to falling edge of SIOCLK. Must be specified as the time to the beginning of
output state change in open drain output mode. See Fig. 6.
