Table 14-402 lists the settings of the AP registers relative to an L4 interconnect firewall. These values are computed based on the physical implementation of each L4 interconnect.
Register Type | Register Name | Bits | Field | Description |
---|---|---|---|---|
Segment | L4_AP_SEGMENT_i_L (2) | 31:0 | BASE | Segment base address |
L4_AP_SEGMENT_i_H (2) | 5:0 | SIZE | Segment size equals to 2SIZE | |
Protection groups | L4_AP_PROT_GROUP_MEMBERS_k_L (3) | 15:0 | CONNID_BIT_VECTOR | For L4ConnID, see Table 14-391. |
L4_AP_PROT_GROUP_ROLES_k_L (3) L4_AP_PROT_GROUP_ROLES_k_H | 31:0 | ENABLE | See Section 14.2.3.7.3 for REQ_INFO description. (1) | |
Region setting | L4_AP_REGION_l_L (4) | 20:0 | BASE | Defines the base address of region with respect to its segment base address |
L4_AP_REGION_l_H (4) | 31:28 | MADDRSPACE | Target interconnect MAddrSpace | |
26:24 | SEGMENT_ID | Segment ID number of the region | ||
22:20 | PROT_GROUP_ID | Protection group member attached to the region | ||
18:17 | BYTE_DATA_WIDTH_EXP | Determines the number of bytes in an access | ||
14:8 | PHY_TARGET_ID | Physical target ID | ||
6:1 | SIZE | Size of the region equals to 2SIZE | ||
0 | ENABLE | Enables the region protection |
