Note 4-1-1: These specifications are theoretical values. Margins must be allowed according to the actual operating
conditions.
Note 4-1-2: In an application where the serial clock input is to be used in the continuous data transfer mode, the time
from SI0RUN being set when serial clock is high to the falling edge of the first 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. 8.
