a.CINT rapid charge After reset canceled, capacity CINT charged rapidly until terminal first falls. b.CH rapid charge After reset canceled, capacity charged rapidly until terminal first rises falls.
c.Stationary light hold After reset canceled, holds stationary light while HOLD terminal HIGH. d.The first integration After reset canceled, HOLD terminal HIGH terminal HIGH, first integration implemented while terminal HIGH. Therefore,the first integration must finished(INT terminal from HIGH LOW) until stationary light hold will completed (HOLD terminal from HIGH LOW) e.The second integration After reset canceled, second integration implemented HOLD terminal terminal HIGH. And,the second integration completed exceeding judgment level CINT terminal although terminal HIGH. (5)SOUT When second integration starts,This terminal becomes from HIGH LOW. CINT terminal exceeds judge level terminal becomes from HIGH LOW, this terminal becomes from HIGH.

Full spec (typical)
This type uses CLALV,STB,RESET,INT,HOLD,SOUT terminal terminal microcomputer. This typical type M52957AFP.
MICROCOMPUTER
Most simplified type
This type does connect CLALV,STB,RESET terminals microcomputer. When above mentioned terminals connected microcomputer without changing mask,connect each terminal ground. this case,clamp level becomes standby function lost. Power reset used reset.
MICROCOMPUTER
Explanation terminal that simplified. (a)CLALV typical type,16way clamp levels external control,but also terminal simplified mask option follows. Clamp level fixation Selects point from steps clamp level fixes (II) Clamp level step Selects points from clamp level switches changing CLALV terminal HIGH/LOW. However,as selecting points,there following constraint.

When standby function required such switched ON/OFF,STB terminal eliminated. Since include power reset circuit,RESET terminal eliminated. merit controlling RESET terminal from outside,distance detection time shortened because there need switch Terminal /OFF consecutive distance detection.
