The DDR-SDRAM space in this LSI and internal registers of this LSI can be accessed by a CPU
externally connected to the LSI (hereinafter, simply referred to as “external CPU”). Access by an
external CPU is implemented using the MPX protocol.

• Control of access from an external CPU
Figure 15.1 shows a block diagram of the EXCPU.
An external CPU is able to access the DDR-SDRAM space and internal registers of this LSI.
The MPX protocol is used for access from an external CPU.
The SH7750 Group and the SH7751 Group can be connected as the external CPU via the buses
of the SH7750 Group and the SH7751 Group.
