(1) DO pin open automatically when end-UC is set and the IF counter starts (CTE = 0→1).
(2) DO pin becomes low, enabling check of the counter end when the IF counter measurement is
over.
(3) DO pin open with serial data input/output (CE pin : Hi)
Note)DO pin open regardless of the DO pin control data (DOC0 to 2) during data input period (IN1
and IN2 modes CE-Hi period).
The DO pin state allows output of the content of internal DO serial data in synchronization with
CL regardless of the DO pin control data (DOC0 to 2) during data input period (OUT mode CE :
