Abstract
An input/output (I/O) circuit or cell associated with a pin of a programmable logic circuit allows the pin to be configured as for bidirectional input and output operations, without requiring a second one-bit register to be configured from the configurable logic elements of the programmable logic circuit. The I/O cell can be used in parallel-to-serial, serial-to-parallel and shift register operations.
