External Wait Mask Specification
Specifies whether or not the external wait input is valid.
The specification by this bit is valid even when the
number of access wait cycle is 0.
0: External wait input is valid
1: External wait input is ignored
Reserved
These bits are always read as 0. The write value
should always be 0.
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
