All,

during schematic design of a MPC8377 based board I stumbled over an issue with the local bus holding various Nor-/Nand-Flash and SRAM devices.

Freescale's eLBC Controller supports muxed and non-muxed addressing modes. All FSL reference schematics are using muxed mode utilizing an address latch and bi-directional data buffer controlled by LBCTRL signal.

The non-muxed mode doesn't need this latching stuff but is limited to 21 address signals ... which would enough for me.

Has anybody done this before or is actively using a system with that kind of eLBC config ? Are there any known issues with non-muxed mode ?

Any hints are welcome.

Regards, André Schwarz
