(2) When CL is stopped at the high level

(Note 1) The input of serial data is taken in at the rising edge of CL, and latched at the falling edge of CE. In addition,

this IC has the function that counts the number of CL clock to receive the correct serial data. That is to say,

because it isn’t latched at the falling edge of CE when the number of the count of CL in each serial data is

wrong, receiving wrong serial data can be prevented.
