3. Initially, all values are altered only in the working memory. Once the values
have been transferred, they must be saved to the EEPROM using the STV com-
mand. Changes to function codes do not become effective until the counter
has been restarted/reset ("RST").
The following sequence should be adhered to when changing values:
- Set basic function (BFN)
- Set default values (F00)
- Set function codes (F01 ... F35)
- Save values to EEPROM (STV)
- Reset/restart counter to activate the changes (RST)
- Set the prescaler (PSC)
- Set the preselect values (PR0 .. PR2)
- Set the counting values (CNT, TOT, SU1, SU2)
- Save all values to EEPROM (STV)
Any function not mentioned here does not have to adhere to a specific
sequence. All read functions can be used at any time.
