The device includes several internal registers which are used for customization and
identification.
The initial signature allows read access to all areas but only write access to customer
registers. 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 to complete.
As there is no check for the programming time, the user must make sure no other
accesses to the EEPROM are made during the programming cycle. 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 programming duration by setting register CTRL1, bit 11
EEP_CP_CLOCK_EN and register TESTCTRL0, bit 11 EEP_WRITE_EN. All register
addresses have to be read out for calculating the checksum. However, some register
addresses are reserved for calibration.
