Recovery cycle (data hold time) control
For some memory, the data hold time after when the
CE
or
OE
signal
is asserted in a
read cycle is defined by the AC specification. This may lead to data conflicts. Thus, to
avoid this problem, a single dummy cycle can be inserted immediately after an access
cycle for the CSm space by setting the BmCSH<BmREC> bit to 1.
This single dummy cycle is inserted when another CS space is accessed in the next bus
cycle.
BnCSH<BnREC>
0
No dummy cycle is inserted (Default).
1
Dummy cycle is inserted.
