-- The ul is not the compatible w/ Mitsubishi 60 pin series cards
-- CD may simply be "card detect" -- the mitsubish cards have a pin
labelled CD which is named "Card Detector" --> Detector for card insertion
or removal. CD is connected to GND for CE type....
The mitsubishi cards also have:
-- a write-protect signal
-- a 3 bit card ID
Does NEC specify the polarity on the CE/WE/OE lines? I would
assume they are negative asserted since almost all memories are that way.
