FSMC in multiplexed mode
2011-05-17 04:03 AM
Hi!
I have question about FSMC controller. Im planning to use it in multiplexed mode to communicate to memories. I have STM103 in 144 pin package, but need the pins elsewhere. The question is: If I configure memory interface according to ''mode muxed- asynchronous access to muxed NOR flash'' in reference manual (with the help of D-latch), does the controller allow 8 bit access to 16 bit wide memory? I mean if I connect 16 bit SRAM in that mode, does the controller use NBL0 and NBL1 signals? At least they are not shown in timing diagram in that mode... Or can I specify memory type as SRAM and enable address multiplexing in FSMC_BCRx register (this kind of timing diagram is missing, at least)? Thank you, Madis
