Description
9:23 PC_MASK_15_TO_1 RW R Undefined This field specifies protection context identifier based
access control.
Bit i: protection context i+1 enable. If '0', protection
context i+1 access is disabled; i.e. not allowed. If '1',
protection context i+1 access is enabled; i.e. allowed.
24:28 REGION_SIZE RW R Undefined This field specifies the region size:
'0'-'6': Undefined.
'7': 256 B region
'8': 512 B region
'9': 1 KB region
'10': 2 KB region
'11': 4 KB region
'12': 8 KB region
'13': 16 KB region
'14': 32 KB region
'15': 64 KB region
'16': 128 KB region
'17': 256 KB region
'18': 512 KB region
'19': 1 MB region
'20': 2 MB region
'21': 4 MB region
'22': 8 MB region
'23': 16 MB region
'24': 32 MB region
'25': 64 MB region
'26': 128 MB region
'27': 256 MB region
'28': 512 MB region
'39': 1 GB region
'30': 2 GB region
'31': 4 GB region
30 PC_MATCH RW R Undefined This field specifies if the PC field participates in the
'matching' process or the 'access evaluation' process:
'0': PC field participates in 'access evaluation'.
'1': PC field participates in 'matching'.
'Matching' process. For each protection structure, the
process identifies if a transfer address is contained
within the address range. This identifies the 'matching'
regions.
'Access evaluation' process. For each protection
structure, the process evaluates the bus transfer
access attributes against the access control attributes.
Note that it is possible to define different access
control for multiple protection contexts by using
multiple protection structures with the same address
region and PC_MATCH set to '1'.
31 ENABLED RW R 0 Region enable:
'0': Disabled. A disabled region will never result in a
match on the bus transfer address.
'1': Enabled.
Note: a disabled address region performs logic gating
to reduce dynamic power consumption.
