A DIFFERENCE WITH RS5C313
The logic of serial clock is point that it become that RS5C313 reverses RS5C314 with SCLK for SCLK and differ-
ence point of RS5C314 and RS5C313, describe is the master of by it being different in the following 3 items
(Give RS5C313 application manual absolutely reference in electric characteristic / the thing AC/DC require-
ments rating / recommendation gesture a maximum.)
