Operand:

D: Current time of RTC (occupies 7 consecutive devices)

Explanations:

1.TRD instruction reads the 7 real-time data of RTC (year (A.D.), day(Mon.Sun.), month, day, hour, minute, second from D1319~D1313 and stores the read data in registers specified by D.

2.Only when power is on can RTCs of SS2 series perform the fuction of timing. The RTC data registers D1319~D1313 are latched. When power is resumed, the RTC will resume the stored time value before power down. Therefore, we suggest users modify the RTC value every time when power is ON.

3.RTCs of SA2/SE V1.0 及 ES2/EX2/SX2 V2.0 series can still operate for one or two weeks after the power is off (they vary with the ambient temperature). Therefore, if the machine has not operated since one or two weeks ago, please reset RTC.

4.D1319 only stores the 2-digit year in A.D. If 4-digit year data is required, please refer to Points to note below.

5.For relative flags and registers please refer to Points to note.

Program Example:

When X0 = ON, TRD instruction reads the current time of RTC to the specified register D0~D6. The content of D1318: 1 = Monday; 2 = Tuesday … 7 = Sunday.
