R/W Description
R
Reserved
These bits are always read as 0. The write value
should always be 0.
R/W SRAM with Byte Selection Byte Access Select
Specifies the WEn and RD/WR signal timing when the
SRAM interface with byte selection is used.
0: Asserts the WEn signal at the read timing and
asserts the RD/WR signal during the write access
cycle.
1: Asserts the WEn signal during the read access cycle
and asserts the RD/WR signal at the write timing.
R
Reserved
These bits are always read as 0. The write value
should always be 0.
