Description
Insert Wait Cycle
These bits specify the number of wait cycles to be
inserted. The wait cycles are as follows when the
SRAM interface, byte control SRAM interface, burst
ROM interface (first data cycle only), or PCMCIA
interface is selected. Insertion of external wait cycles by
the RDY pin is not possible when "no cycle inserted" is
selected.
0000: No cycle inserted
0001: 1 cycle inserted
0010: 2 cycles inserted
0011: 3 cycles inserted
0100: 4 cycles inserted
0101: 5 cycles inserted
0110: 6 cycles inserted
0111: 7 cycles inserted
When MPX interface is selected, the wait cycles are
inserted as follows according to the IW[2:0] setting. The
IW[3] setting is invalid. The external wait cycles can be
inserted by the RDY pin in any settings.
IW[2] specifies wait cycle insertion for the second and
subsequent data:
0: No cycle inserted
1: 1 cycle inserted
IW[1:0] specifies wait cycle insertion for the first data:
00: 1 cycle inserted in reading and no cycle inserted in
01: 1 cycle inserted in reading and 1 cycle inserted in
10: 2 cycles inserted in reading and 2 cycles inserted in
11: 3 cycles inserted in reading and 3 cycles inserted in
