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.
