Register Name | DOMAIN_ISO_CNTRL |
---|---|
Relative Address | 0x00000000F0 |
Absolute Address | 0x00FFD600F0 (PMU_LOCAL) |
Width | 32 |
Type | mixedMixed types. See bit-field details. |
Reset Value | 0x00000028 |
Description | Isolation Wall Enable Control. Reset only by POR. |
Controls the Isolation walls for various power domains and subsystems. 0: not isolated. 1: isolated. The register maintains its contents during a System Reset.
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
LP_FP_Locked | 31 | rwsoRead/write, set only | 0x0 | Isolates the FPD-PL domains by clamping all inputs to each domain. Once this bit is set, the FPD-PL remain isolated until POR is asserted. |
Reserved | 30:6 | roRead-only | 0x0 | reserved |
FP_PL | 5 | rwNormal read/write | 0x1 | Isolates the FPD-PL domains by clamping all inputs to each domain to their disabled values (1=Isolated) |
LP_PL_PCAP | 4 | rwNormal read/write | 0x0 | Isolates the LPD-PL domains of the PCAP interface signals by clamping all inputs to each domain to their disabled values. This is used mainly during power-down of the PL. |
LP_PL_Non_PCAP | 3 | rwNormal read/write | 0x1 | Isolates the LPD-PL domains by disabling interface signals except the ones associated with the PCAP subystem by clamping all inputs to each domain to their disabled values. This is used during Partial Reconfiguration of the PL. |
LP_FP_2 | 2 | rwNormal read/write | 0x0 | Isolates the LPD-FPD domains by disabling interface signals that includes Clock, Resets and Controls that may have to be unisolated while the rest of the interface stays in isolation. |
LP_FP_1 | 1 | rwNormal read/write | 0x0 | Isolates the LPD-FPD domains by disabling interface signals except the ones that are controlled by the [LP_FP_2] bit. |
PMU | 0 | rwNormal read/write | 0x0 | Isolates the PMU from the rest of the LPD. Clamps all inputs to the PMU to their disabled values. |
