A method and apparatus are disclosed, in an interactive broadband set-top box receiving broadband signals from a headend, to facilitate communications with an installed card within the set-top box using a single IC chip that processes the broadband signals. The single IC chip is configured to a PCMCIA PC-card mode such that PC card signals are multiplexed to certain I/O pins of the single IC chip. In the PCMCIA PC-card mode, the single IC chip attempts to detect the presence of and identify an installed card in the set-top box. If an installed card is present and is identified as a POD module, then the single IC chip is reconfigured from the PCMCIA PC-card mode to a POD mode such that POD-compatible signals are multiplexed to certain existing I/O pins of the single IC chip when operating in the POD mode.
