Programming
To program date and time it is advisable to use the functions provided by
JetSym STX:
 DateTimeActual()

DateTimeDecode()
 DateTimeEncode()
 DateTimeIsValid()
 DateTimeSet()
For more information on these functions refer to the JetSym online help.
If you make use of the above functions, the minimum time interval is one
second. If you need a time interval of one second, programming must be
made by using the registers described below.
Depending on the respective application, access to the real-time clock via
registers might be required. For this, there are two register sets:

Register set 1 is for directly accessing individual real-time clock values.
 Changes to values in register set 1 are immediately transferred to the
real-time clock.

Register set 2 operates within a buffer. In the buffer, all real-time clock
values are consistently read out and written.
 Not before the trigger register is written to, the value changes made in or
out of register set 2 are transferred.
The following registers have been assigned to the real-time clock:
Register set 1: Direct access
