addressed register. As the sensor registers are 32 bits wide, the read and write
transfers are generally 4 bytes long. However, 1, 2 or 3 byte transfers are allowed.

Memory map

The DPS 5000 sensor registers are mapped within a 1 kbyte memory space. As each
register is 4 bytes wide, the register addresses range from 0 to 255. Not all the
address space is available to the user, some addresses are reserved whilst others
are unused. The reserved addresses cannot be written to and read as 0x00000000.
Unused addresses cannot be written to and read as 0xFFFFFFFF.
The registers are grouped into 3 blocks: volatile data, configuration data and
coefficient data as shown in Table 3.
