The device includes several internal registers, which are used for purposes, such as
customization and identification.
The initial signature allows read access to all areas, but write access just to customer
registers only. Write accesses to reserved areas are ignored. Since these registers are
implemented as EEPROM cells, writing to the registers needs a specific time t
each write access.
Since there is no check for the programming time, the user has to take care that no other
access to the EEPROM is done during the programming. The EEPROM must not be
addressed during the time t
Note: Before data can be stored in the EEPROM, the internal charge pump has to be
switched on for the duration of programming by setting register CTRL1, bit 11
EEP_CP_CLOCK_EN, as well as register TESTCTRL0, bit 11 EEP_WRITE_EN. For
calculating the checksum, all register addresses have to be read out and consulted,
although some of them are reserved for calibration purposes.
