What does the phrase 'the DMA interface cannot access the AHB bus' in the TRM mean ?

Applies to: ARM968E-S

Answer

The DMA interface is an AHB-Lite slave interface which is just used for putting data into the DTCM. There is no direct connection between the DMA interface and the AHB-Lite Master interface, you can't access the AHB via the DMA interface.
