0' = parity bits; '1' = user data.
Mask of address bits [20:16] to be used to
generate parity for the data memory. A '1' in one
of these bits indicates that the corresponding
address bit will be used to generate parity.
Reserved. Always read as "0"
Mask of data bits to be used to generate parity
for the data memory. A '1' in one of these bits
indicates that the corresponding data bit will be
used to generate parity.
