Re: GAL's and PALASM
As i write, it is my experience.
Lattice says for his GALs:
The GAL16V8 input and I/O pins have built-in active pull-ups. As
a result, unused inputs and I/O's will float to a TTL "high" (logical
"1"). Lattice Semiconductor recommends that all unused inputs
and tri-stated I/O pins be connected to another active input, VCC,
or Ground. Doing this will tend to improve noise immunity and reduce
ICC for the device.
