Macrocell
There are two fundamental types of macrocell: the output macrocell and the buried macrocell. The
buried macrocell is only found in MACH 2 devices. The use of buried macrocells effectively
doubles the number of macrocells available without increasing the pin count.
Both macrocell types can generate registered or combinatorial outputs. For the MACH 2 series,
a transparent-low latch configuration is provided. If the register is used, it can be configured as
a T-type or a D-type flip-flop. Register and latch functionality is defined in Table 9.
Programmable polarity (for output macrocells) and the T-type flip-flop both give the software a
way to minimize the number of product terms needed. These choices can be made automatically
by the software when it fits the design into the device.
