nLDEV
Address Strobe is connected directly to the VL bus. nCYCLE is
created typically by using nADS delayed by one LCLK.
Typically uses the interrupt lines on the ISA edge connector of
VL bus
32 bit data bus. The bus byte(s) used to access the device are a
function of nBE0-nBE3:
nBE0
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.
