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 access
001: 0 cycles
010: 1 cycle
011: 2 cycles
100: 3 cycles
101: 4 cycles
110: 5 cycles
111: 6 cycles
Reserved
These bits are always read as 0. The write value should
always be 0. If 1 is written to these bits, correct operation
cannot be guaranteed.
Number of Delay Cycles from Address, CSn Assertion to RD,
WEn Assertion
Specify the number of delay cycles from address and CSn
assertion to RD and WEn assertion.
00: 0.5 cycles
01: 1.5 cycles
10: 2.5 cycles
11: 3.5 cycles
