Abstract: An integrated circuit package including a plurality of macrocells for connecting a logic circuit of the package to a plurality of external contacts of the package. At least one of the macrocells has an output driver that is enabled or disabled by a control signal for transmitting or preventing transmission of a logic signal to one of the contacts. The control signal is generated by a logic gate that receives and logically combines an individual output enable signal dedicated to that particular macrocell with a selected signal. One signal that may be selected is a regional output enable signal that is supplied to more than one macrocell. Each macrocell also has a feedback multiplexer selecting one signal to be sent to the logic circuit. Choices include a nonstored logic signal, a stored logic signal from a flip-flop register in the macrocell, a signal applied to the external contact associated with that macrocell, and a signal applied to another external contact associated with a different macrocell.
