Description
Area 2 Wait Control 2 to 0
These bits select the number of program wait
states when accessing area 2 while AST2 bit in
ASTCR = 1.
A CAS latency is set when the synchronous DRAM
is connected * . The setting of area 2 is reflected to
the setting of areas 2 to 5. A CAS latency can be
set regardless of whether or not an ASTCR wait
state insertion is enabled.
000: Program wait not inserted
001: 1 program wait state inserted
010: 2 program wait states inserted
011: 3 program wait states inserted
100: 4 program wait states inserted
101: 5 program wait states inserted
110: 6 program wait states inserted
111: 7 program wait states inserted
000: Synchronous DRAM of CAS latency 1 is
