P-Port MMIO Data Registers
These registers together form a 32-bit data word for accessing the FX3 internal MMIO space. Only full 32-bit accesses are
supported to FX3 registers. The bits PP_MMIO.MMIO_RD, PP_MMIO.MMIO_WR, PP_MMIO.MMIO_DONE are used to con-
trol the operation.
Reading from these registers will return the data from the last MMIO_RD operation or the data written by Application Proces-
sor, whichever is more recent.
