Part Number
Bus Matrix Connections
Flash Memory Parameters
Accesses to unused areas returns an error result to the master requesting such an access.
The bus matrix has the several masters and slaves. Each master has its own bus and its own
decoder, thus allowing a different memory mapping per master. The master number in the table
below can be used to index the HMATRIX control registers. For example, MCFG0 is associated
with the CPU Data master interface.
Table 9-3.
Each slave has its own arbiter, thus allowing a different arbitration per slave. The slave number
in the table below can be used to index the HMATRIX control registers. For example, SCFG3 is
associated with the Internal SRAM Slave Interface.
