8.23 Host Interface Memory Registers Description
The software device driver communicates with the manageability block through CSR access.
8.23.1 Host Slave Command Interface to Manageability Firmware
This interface is used by the software device driver for several of commands and for delivering various
types of data structure in both directions (MNG Host, Host  MNG).
The address space is separated into two areas:
1. Direct access to the internal ManagementDATA RAM: The internal DATA RAM is mapped to address
0x8800-0x8EFF. Writing to this address space goes directly to the RAM. This section can be limited
by the internal firmware. The firmware reports to the host the maximum size allocated in the
HIBSMAXOFF register. When this section is used for host interface commands (Section 10.8.2.4) it
is usually limited to 512 bytes. When it is used to load firmware in systems (Section 3.4.3), the full
1792 bytes are available.
2. Control registers located at address 0x8F00.
