Abstract
A pin control unit and a plurality of addressable storage locations are provided to an integrated circuit to control the input/output (I/O) pins of a functional block of the integrated circuit or the I/O pins of the integrated circuit. Multiple ones of the addressable storage locations are correspondingly coupled to I/O buffers associated with the I/O pins. The pin control unit selectively loads bit values into appropriate ones of the addressable storage locations. In response, the I/O buffers input bit values from and/or output bit values to the corresponding I/O pins. The pin control unit controls subsets of the I/O pins in a coordinated manner as I/O ports. The pin control unit also controls data movement between the addressable storage locations and various temporary storage elements of the functional block/integrated circuit.
