Matrix Slaves
Masters to Slaves Access
Each Slave has its own arbiter, thus allowing a different arbitration per Slave to be programmed.
Table 6-2.
All the Masters can normally access all the Slaves. However, some paths do not make sense,
such as allowing access from the Ethernet MAC to the internal peripherals. Thus, these paths
are forbidden or simply not wired, and shown “-” in the following tables.
The four DDR ports are connected differently according to the application device.
The user can disable the DDR multi-port in the DDR multi-port Register (bit DDRMP_DIS) in the
Chip Configuration User Interface.

• When the DDR multi-port is enabled (DDRMP_DIS=0), the ARM instruction and data are
• When the DDR multi-port is disabled (DDRMP_DIS=1), DDR Port 1 is dedicated to the LCD
respectively connected to DDR Port 0 and DDR Port 1. The other masters share DDR Port 2
and DDR Port 3.
