Description
Number of Wait Cycles from ACTV Command to
READ (A)/WRIT (A) Command
Specify the number of minimum wait cycles from issuing
the ACTV command to issuing the READ (A)/WRIT (A)
command. The setting for areas 2 and 3 is common.
00: 0 cycle
01: 1 cycle
10: 2 cycles
11: 3 cycles
Reserved
This bit is always read as 0. The write value should always
be 0.
