3.5.2.1 Number of masters
The Flash Memory Controller supports up to eight crossbar switch masters. However,
this device has a different number of crossbar switch masters. See Crossbar Switch
Configuration for details on the master port assignments.
3.5.2.2 Program Flash Swap
On devices that contain program flash memory only, the program flash memory blocks
may swap their base addresses.
While not using swap:
• FMC_PFB0CR controls the lower code addresses (block 0)
• FMC_PFB1CR controls the upper code addresses (block 1)
If swap is used, the opposite is true:
• FMC_PFB0CR controls the upper code addresses (now in block 0)
• FMC_PFB1CR controls the lower code addresses (now in block 1)
