Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Byte Access Selection for Byte-Selection SRAM
Specifies the WEn (BEn) and RD/WR signal timing when
the byte-selection SRAM interface is used.
0: Asserts the WEn (BEn) signal at the read/write timing
1: Asserts the WEn (BEn) signal during the read/write
Reserved
This bit is always read as 0. The write value should always
be 0.
Number of Write Access Wait Cycles
Specify the number of cycles that are necessary for write
access.
000: The same cycles as WR3 to WR0 setting (read or
001: 0 cycles
