System area of I.CODE2 chip
This section describes a system area of I.CODE SLI chip. The system
area of I-CODE SLI chip is allocated in the other area rather than user
memory area.
Execute a specific command to access to the system area.
The processes in the system area are done by specific commands instead
of page number allocations.
