Functional description
The STLM75 registers have unique pointer designations which are defined in

All of these user-accessible registers can be accessed via the digital serial interface at

Registers and register set formats
Command/pointer register
The most significant bits (MSBs) of the command register must always be zero. Writing a '1'
into any of these bits will cause the current operation to be terminated (bit 2 through bit 7
must be kept '0', see
Table 4.
The command register retains pointer information between operations (see
Therefore, this register only needs to be updated once for consecutive READ operations
from the same register. All bits in the command register default to '0' at power-up.
