Description
Number of Delay Cycles from RD, WEn (BEn) negation to
Address, CSn negation
Specify the number of delay cycles from RD and WEn
(BEn) negation to address and CSn negation.
00: 0.5 cycle
01: 1.5 cycles
10: 2.5 cycles
11: 3.5 cycles
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
These bits are always read as 0. The write value should
always be 0.
and asserts the RD/WR signal during the write access
cycle.
