ABSTRACT:
There is provided a semiconductor device for multiplexing across a plurality of shared Input/Output (I/O) pins. The semiconductor device comprises a first core for operation of a first function, a second core for operation of a second function, a multiplexer and an additional hardware module. The multiplexer is arranged to set the I/O pins to the first function or to the second function at power up. The hardware module comprises an arbiter arranged to receive requests from the cores for use of the I/O pins and to grant use of the I/O pins to a selected core as required. Thus, the hardware module can switch functions dynamically and dual mode multiplexing is enabled.
