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/Os 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 capability. De-
Note: The development software configures all of the architecture control bits and checks for proper pin usage automatically.

signs requiring eight I/Os 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.
