Dedicated Input in a Non-Registered Device
The control bit settings are SG0 = 1, SG1 = 0 and SL0x = 1. The output buffer is disabled. The
feedback signal is an adjacent I/O pin.
Combinatorial I/O in a Non-Registered Device
The control settings are SG0 = 1, SG1 = 1, and SL0x = 1. Only seven product terms are available
to the OR gate. The eighth product term is used to enable the output buffer. The signal at the
I/O pin is fed back to the AND array via the feedback multiplexer. This allows the pin to be used
as an input.
Combinatorial I/O in a Registered Device
The control bit settings are SG0=0,SG1=1 and SL0x =1. Only seven product terms are available
to the OR gate. The eighth product term is used as the output enable. The feedback signal is the
corresponding I/O signal.
