5.4 Read A/D conversion result or NVM data

To read out the temperature data word UT (16 bit), the pressure data word UP (16 to 19 bit) and

the NVM data proceed as follows:

After lowering CSB, the master send the read command with the register start address.

NVM data registers:

0xAA (to read 0xAA – 0xBF)

ADC results UT or UP: 0xF6 (to read 0xF6 – 0xF7, optionally 0xF8)

After writing the read command + register address, the master sends further clock cycles in order to

allow for the BMP183 to output the data to the SDO pin.

For ultra high resolution, the XLSB register with address 0xF8 can be read to extend the 16 bit word

to up to 19 bits.
