Note 4-1-1: These specifications are theoretical values. Add margin depending on its use.
Note 4-1-2: When using serial clock input under continuous data transmission/reception mode, the time from SI0RUN
is set while serial clock is “H” to the first falling edge of 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.
