Bits Description
31:24
Master Region Write Access: Each bit [31:24] corresponds to Regions [7:0]. If the bit is set, this
master can erase and write that particular region through register accesses.
Bit 23 is a don’t care as the primary master always has read/write permission to it’s primary region
23:16
Master Region Read Access: Each bit [23:16] corresponds to Regions [7:0]. If the bit is set, this
master can read that particular region through register accesses.
Bit 17 is a don’t care as the primary master always read/write permission to it’s primary region.
15:0
Requester ID: This is the Requester ID (Bus/Device/Function Number_ of the Host CPU
For the host CPU, this should be set to Bus/Device/Function: 0/0/0
