Note 4-1-1: These specifications are theoretical values. Margins must be allowed according to the actual operating
conditions.
Note 4-1-2: Specified with respect to the falling edge of SIOCLK. Specified as the time up to the time the output state is
changed in the open drain output mode. See Fig. 6.
