Extended cardbus/PC card controller with split-bridge technology

摘要

An interface (20) comprises first electronics (26) adapted to interface parallel data from a parallel data bus (32) to a first bus, the first electronics (26) being adapted to connect to at least one PC card. The interface further comprises second electronics (30) adapted to interface parallel data from said parallel data bus (32) into serial data adapted to interface with a second remote bus, said second electronics (30), in the absence of a threshold detect signal from the second remote bus, converting said parallel data to said serial data without requiring any signal from said second remote bus. The interface (20) comprises electronics shared by the first electronics (26) and the second electronics (30) to interface to the parallel data bus (32).
