REGISTER AND EEPROM DATA ADDRESSES (continued)
Temperature
sensor
configuration
register
gain trim settings. Temperature and pressure offset
trim register (FE/7EHEX) is for storing the temperature
and pressure measurement ADC offset trim settings.
The last Clock oscillator frequency trim register
(FF/7FHEX) is for internal 250 kHz clock oscillator
trimming. It is only for testing purpose since the
internal clock oscillator is factory trimmed.
(FB/7BHEX) is for storing the temperature sensor
selection and bridge resistance trim settings.
Pressure gain trim register (FC/7CHEX) is for storing
pressure measurement AFE gain trim settings.
Similarly Temperature gain trim register (FD/7DHEX
is for storing the temperature measurement AFE
)
Following chapters desribe the twenty registers more detailed.
RESET REGISTER (EC/6CHEX
)
The Reset register is for resetting the device via
serial bus. The reset will take place immediately after
any data byte is written to the address EC/6CHEX via
the I2C or SPI serial bus interface. The reset
initializes internal counters and the serial
communication bus and resets all registers from
FF/7FHEX to EC/6CHEX to a default zero (00HEX) value.
Reading from the reset register is not possible since
it does not contain any data.
