Macrocell
Each XC9500 macrocell may be individually configured for
a combinatorial or registered function. The macrocell and
associated FB logic is shown in
Five direct product terms from the AND-array are available
for use as primary data inputs (to the OR and XOR gates) to
implement combinatorial functions, or as control inputs
including clock, set/reset, and output enable. The product

The macrocell register can be configured as a D-type or
T-type flip-flop, or it may be bypassed for combinatorial
operation. Each register supports both asynchronous set
and reset operations. During power-up, all user registers
are initialized to the user-defined preload state (default to 0
if unspecified).
