Description
Number of Access Wait Cycles
Specify the number of wait cycles that are necessary for
read/write access.
0000: 0 cycle
0001: 1 cycle
0010: 2 cycles
0011: 3 cycles
0100: 4 cycles
0101: 5 cycles
0110: 6 cycles
0111: 8 cycles
1000: 10 cycles
1001: 12 cycles
1010: 14 cycles
1011: 18 cycles
1100: 24 cycles
1101: Reserved (setting prohibited)
1110: Reserved (setting prohibited)
1111: Reserved (setting prohibited)
External Wait Mask Specification
Specify whether or not the external wait input is valid. The
specification by this bit is valid even when the number of
access wait cycles is 0.
0: External wait is valid
1: External wait is ignored
Reserved
These bits are always read as 0. The write value should
always be 0.
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
