NOTES
32 bit data bus. The bus byte(s) used to access the device are a function
of nBE0-nBE3:
Not used = tri-state on reads, ignored on writes. Note that nBE2 and
nBE3 override the value of A1, which is tied low in this application.
nLDEV is a totem pole output. nLDEV is active on valid decodes of A15-
A4 and AEN=0.
