Write Typed Data (Function Index 30)

This _DSM Interface for Byte Addressable Energy Backed Function Class (Function Interface 1) function writes a 32-byte block inside a typed block data region. This functionality enables scenarios that require the use of vendor-specific registers. It's also used for debugging.

Registers are defined in the Byte Addressable Energy Backed Interface specification.
