Hello,

 

We are using ADuc7126 for a project that now requires external RAM and flash due to new requirements.  Currently, most of the address lines are currently being used for I/Os as well as AE, /RS, and /WS.  What's the best way to work around this?  Is there any other options besides reroute the I/O lines to an external SPI to GPIO expander?  Or keep things the same and use I2C or SPI memory interfacing?  I appreciate any suggestions!
