The masters connected to the crossbar switch are assigned as follows:
Master module
Master port number
ARM core code bus
0
ARM core system bus
1
DMA /EzPort
2
USB OTG
4
NOTE
The DMA and EzPort share a master port. Since these modules
never operate at the same time, no configuration or arbitration
explanations are necessary.

The slaves connected to the crossbar switch are assigned as follows:
Slave module
Slave port number
Flash memory controller
0
SRAM controllers
1,2
Peripheral bridge 0/GPIO
