16.4.2.1.1. Data Slave Remapping Example

Data Slave Remapping Example

To remap the data slave to access other 1 MB regions of the flash device, enable address remapping in the enable Arm* AMBA* advanced high speed bus ( AHB* ) address remapping field (enahbremap) of the cfg register. All incoming data slave accesses remap to the offset specified in the remap address register (remapaddr).

The 20 LSBs of incoming addresses are used for accessing the 1 MB region and the higher bits are ignored.

Note: The quad SPI controller does not issue any error status for accesses that lie outside the connected flash memory space.
