For signal definitions and protocol,
see the AMBA AXI Protocol Specification. When user parity is
enabled, drive the correct parity value on WDATA_PARITY for Write transactions. The
RDATA_PARITY bus provides the Read data parity along with the Read data. The parity
calculation is done on a per-byte basis where a 1 is asserted if the sum of the bits in a byte
is Odd.
Each AXI port can accept 64 read transactions and 32 write transactions.
