Please excuse my newbie questions.

I am working on a project that will use an 89C55WD which is an Atmel 8051 variant.

I need more than the 128/256 bytes of RAM. I have seen that 8051 supports up to 64K or external RAM.

These two articles describe adding 64K of RAM.

Is support built into SDCC for using the external 64K of RAM? Are there any flags or switches that I need to use to use external RAM instead of built in 128/256 RAM bytes?

Thanks,

Mike
