grounding the ID pin will disable LCIM and the module will be configured as a multi-chip module.

I named this pin ID because it affects the response of the chip to the C=ID opcode.
Of course I didn't know the actual name of the pin, and LCIM would be a better name.
I suspect that other pins are defining the memory type and size, and thus the global response of the chip to C=ID.
