A.4.2 Configuration Registers
Default power-up values (registers 773 ... 775) are written into non-
volatile EEPROM memory. The EEPROM memory implementation has a limit of
30000 writes, and is intended to be used only when saving long-term or
permanent configurations. Use the volatile memory (registers 769 ... 771, values
cleared on power-up) for non-permanent configurations (for example, if the
probe is used in a system that regularly updates the given values).
