In the Complex mode, macrocells are configured as output only or
I/O functions.
Architecture configurations available in this mode are similar to the
common 16L8 and 16P8 devices with programmable polarity in
each macrocell.
Up to six I/O's are possible in this mode. Dedicated inputs or
outputs can be implemented as subsets of the I/O function. The
two outer most macrocells (pins 12 & 19) do not have input capa-
Note: The development software configures all of the architecture control bits and checks for proper pin usage automatically.

bility. Designs requiring eight I/O's can be implemented in the
Registered mode.
All macrocells have seven product terms per output. One product
term is used for programmable output enable control. Pins 1 and
11 are always available as data inputs into the AND array.
The JEDEC fuse numbers including the UES fuses and PTD fuses
are shown on the logic diagram on the following page.
