Registered Output Configuration

Each Macro Cell of the ABT22V10A includes a D-type flip-flop for

data storage and synchronization. The flip-flop is loaded on the

LOW-to-HIGH transition of the clock input. In the registered

configuration (S1 = 0), the array feedback is from Q of the flip-flop.

Combinatorial I/O Configuration

Any Macro Cell can be configured as combinatorial by selecting the

multiplexer path that bypasses the flip-flop (S1 = 1). In the

combinatorial configuration, the feedback is from the pin.

Variable Input/Output Pin Ratio

The ABT22V10A has twelve dedicated input lines, and each Macro

Cell output can be an I/O pin. Buffers for device inputs have

complementary outputs to provide user-programmable input signal

polarity.
