7.2.4 Receive Status Base Address Register (RxStatus - 0xFFE0 010C)
7.2.5 Receive Number of Descriptors Register (RxDescriptor - 0xFFE0 0110)
7.2.6 Receive Produce Index Register (RxProduceIndex - 0xFFE0 0114)
The receive descriptor base address is a byte address aligned to a word boundary i.e.
LSB 1:0 are fixed to ’00’. The register contains the lowest address in the array of
descriptors.
The receive descriptor base address is a byte address aligned to a word boundary i.e.
LSB 1:0 are fixed to ’00’. The register contains the lowest address in the array of
descriptors.
Table 209. receive Status Base Address register (RxStatus - address 0xFFE0 010C) bit
The receive status base address is a byte address aligned to a double word boundary i.e.
LSB 2:0 are fixed to ’000’.
The Receive Number of Descriptors register (RxDescriptorNumber) has an address of
0xFFE0 0110. Its bit definition is shown in
Table 210. Receive Number of Descriptors register (RxDescriptor - address 0xFFE0 0110) bit
The receive number of descriptors register defines the number of descriptors in the
descriptor array for which RxDescriptor is the base address. The number of descriptors
should match the number of statuses. The register uses minus one encoding i.e. if the
array has 8 elements, the value in the register should be 7.
The Receive Produce Index register (RxProduceIndex) is a Read Only register with an
address of 0xFFE0 0114. Its bit definition is shown in
Table 211. Receive Produce Index register (RxProduceIndex - address 0xFFE0 0114) bit
