Question 1: 

What pripherals are " master pripheral"?

Question 2:

All accesses to external memory(DDR3 & EMIF) is doing by MSMC, am I thinking right?

Question 3:

Can we program the registers that mentioned in the document?

    In general, masters are elements that can put a request (either read or write) on the bus and in general (not always) slaves are memories.

    So CPU either DSP or ARM as well as any DMA can be a master. In particular, peripherals that have DMA as part of the peripheral are masters. For example, SRIO direct IO, PKTDMA, EDMA, PCI and so on and so forth, they are all masters

    And Rajasekaran K is right about 2 and 3

    Regards
