Flexible static memory controller (FSMC)
transfers at even addresses: nCE1 will be asserted low, NCE2 will be asserted high
and only the even bytes will be valid.
•
Accesses to I/O space can be either 8-bit or 16 bit AHB accesses.

FMC Bank 4 gives access to those 3 memory spaces as described in
Flash memory/PC Card address mapping
and timing
Wait feature
The CompactFlash or PC Card may request the FMC to extend the length of the access
phase programmed by MEMWAITx/ATTWAITx/IOWAITx bits, asserting the nWAIT signal
after nOE/nWE or nIORD/nIOWR activation if the wait feature is enabled through the
277/1080
