Temperature

sensor

configuration

(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

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.

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.
