8bit SRAM howto
I'm wondering what would be the best way to connect an 8 bit SRAM chip to the
This sram is battery backed-up, used for non-volatile status storage.
The best way I've found so far is in 16bit bytewise write enable mode.
But something like an 8bit bytewise write enable mode would be better ;-)
I could write a driver that makes sure that bytes written to the device are
translated to 16bit aligned write's to the SRAM, but I'm afraid that
implementing an mmap method would be impossible.
I noticed that the shared ram interface can be configured to use 8bit mode,
would it make any difference to configure this battery-backed-up SRAM chip as
a shared RAM?
But I guess that does not have any effect on to the way the etrax accesses the
