MACH 1 & 2 Families
The output macrocell (Figure 3) sends its output back to the switch matrix, via internal feedback,
and to the I/O cell. The feedback is always available regardless of the conguration of the I/O cell.
This allows for buried combinatorial or registered functions, freeing up the I/O pins for use as
inputs if not needed as outputs. The basic output macrocell congurations are shown in Figure 4.
The buried macrocell (Figure 5) does not send its output to an I/O cell. The output of a buried
macrocell is provided only as an internal feedback signal which feeds the switch matrix. This
allows the designer to generate additional logic without requiring additional pins. The buried
macrocell can also be used to register or latch inputs. The input register is a D-type ip-op; the
input latch is a transparent-low D-type latch. Once congured as a registered or latched input, the
buried macrocell cannot generate logic from the product-term array. The basic buried macrocell
congurations are shown in Figure 6.
