9.3.14 FPP Filtering Start Address Registers 0-3

The FPP Filtering Start Address Registers provide the filtering start address of the FPP that corresponds to the core.

Usage constraints
These registers are read-only. The filtering start address must be lower than the filtering end address of the FPP that corresponds to the core.
Configurations
Available when the FPP of the corresponding core is implemented.

Bits Name Function
[31:20] Filtering start address

Filtering start address for core 0-3.

The default value is the value of FPFILTERSTARTx, where x corresponds to either core 0, 1, 2 or 3, sampled when the core exits reset. The value on the input gives the upper address bits with 1MB granularity.
