*1 Use the dedicated commands for extended registers to read/write extended file registers from/to ACPU.
*2 The devices for the five types of commands (BM, JM, WM, QM, EM) for registering monitor data can be registered simultaneously in
C24 for each interface.
ACPU common command, AnA/AnUCPU common command
ACPU common command is a communication function issued by MC protocol. The command is accessible for ACPU.
AnA/AnUCPU common command is a command for AnACPU and AnUCPU. The command cannot be executed for other
than AnA/AnUCPU.
: Executable, : Executable (with restrictions), : Not executable
Type
ACPU common command
AnA/AnUCPU common command
When accessing modules other than ACPU, there is a restriction for the accessible device range.
