• (Note 4-4-2)
Note 4-4-1: These specifications are theoretical values. Margins must be allowed according to the actual operating
conditions.
Note 4-4-2: In an application where the serial clock input is to be used in the continuous data transfer mode, the period
from the time SI9RUN is set with the serial clock set high to the falling edge of the first serial clock must
be longer than tSCKHA.
