13.3.3.14 GPL Base Address Register 0
The GPL base address register 0 is provided to allow access to local memory space. This register is closely
tied to PIBAR0 and PIWAR0 in the CSR memory space. A write to GPL base address register 0 also causes
a change in the base address bits that are not masked according to the IWS field of PIWAR0 in PIBAR0.
Note that this write operation will not change the bits that are masked by the IWS field. For read operation
these masked bits will always return zeros.

13.3.3.15 GPL Base Address Registers 1–2
The general purpose local access base address registers are provided to allow access to local memory
space. These registers are closely tied to PIBARn and PIWARn in the CSR memory space. A write to a
GPL base address register also causes a change in the base address bits that are not masked according to
the IWS field of PIWARn in the corresponding PIBARn. Note that this write operation will not change the
bits that are masked by the IWS field. For read operations, these masked bits always return zeros.

Base address. Defines the base address for the inbound window. Bits 11–4 are hard-wired to 0 since
the minimum window size is 4 Kbytes.
Prefetchable. This bit is read-only and contains the value of the PF bit in PIWAR0.
