Provides module test circuit

At power interrupt, data hold up > 1.0s

(between V_DDand V_SSconnect a 0.1mF capacitor)

Built-in power on reset function

General Description

The 6-Digital Timer is a camera data optical printer. Dis-

playing and printing of data (Year Month Day/Day Hour:

Minute/OFF/Month Day Year/Day Month Year) can be

selected by mode selection. Date updating is a fully au-

tomatic calendar from the year 1998.1.1 to 2049.12.31.
