In the Registered mode, macrocells are configured as dedicated
registered outputs or as I/O functions.
Architecture configurations available in this mode are similar to the
common 16R8 and 16RP4 devices with various permutations of
polarity, I/O and register placement.
All registered macrocells share common clock and output enable
control pins. Any macrocell can be configured as registered or I/
O. Up to eight registers or up to eight I/O's are possible in this mode.
Note: The development software configures all of the architecture control bits and checks for proper pin usage automatically.

Dedicated input or output functions can be implemented as sub-
sets of the I/O function.
Registered outputs have eight product terms per output. I/O's have
seven product terms per output.
The JEDEC fuse numbers, including the User Electronic Signature
(UES) fuses and the Product Term Disable (PTD) fuses, are shown
on the logic diagram on the following page.
