Description
These bits are always read as 0. The write value
should always be 0.
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
1: Asserts the WEn signal during the read access cycle
Reserved
This bit is always read as 0. The write value should
always be 0.
Specify the number of cycles that are necessary for
write access.
