Meaning of the entries in the table:
● Offset: Offset to the base value of the peripheral inputs in bytes
● High nibble: Bits 4 -7:
● Low nibble: Bits 0-3
● Value: Position of the relevant number
– Year, month, day, hour, minute and second are two-digit (tens + ones)
– Milliseconds are three-digit (hundreds + tens + ones)
● Status: Status of the time information
Format of "Status"
The status of the time information is available in the four bits of the low nibble of byte 8. The
following table shows the meaning and the values of the status.
Table 1- 7 Status bits of the time (low nibble of byte no. 8)
Bit No. 3 2 1 0
Meaning Prewarning bit Not defined Daylight saving
time (DS), standard
time (ST)
Validity of the time
Value 0 = -
1 = prewarning:
Changeover at the
next full hour
(DS -> ST or ST -
> DS)
0 = ST
1 = DS
0 = invalid
1 = time valid
