Description
Delay Cycles from RD, WEn Negation to Address,
CSn Negation
Specify the number of delay cycles from RD and WEn
negation to address and CSn negation.
00: 0.5 cycles
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-Selection SRAM Byte Access Selection
Specifies the WEn and RD/WR signal timing when the
byte-selection SRAM interface is used.
0: Asserts the WEn signal at the read timing and
1: Asserts the WEn signal during the read/write access
Reserved
These bits are always read as 0. The write value
should always be 0.
Number of Delay Cycles from Address, CSn Assertion
to RD, WEn Assertion
Specify the number of delay cycles from address, CSn
assertion to RD and WEn assertion.
00: 0.5 cycles
01: 1.5 cycles
10: 2.5 cycles
11: 3.5 cycles
asserts the RD/WR signal during the write access
cycle.
