Functional description
The STDS75 registers have unique pointer designations which are defined in

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

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 (see
The command register retains pointer information between operations. 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.
