I looked at the FlexROM III, it appears to emulate just flat 8 or 16
bit devices. PLCC's are more complicated, they frequently make use of
an LPC interface that clocks in 4 bits of data at a time (as I recall)
to get the address into the chip, then clocks out 4 bits of data at a
time. I think an operation is 16 bits at a time. This is all transparent
from the system's perspective. However behind the scenes it is a
complicated dance.

LPC = Low Pin Count
