摘要：An interface unit for communicating between a programmable device, such as ahearing assisting device, and a programmer unit employs a circular shift register (16) anda memory (18). Upon initialization the memory contents are loaded in the circular shiftregister and cycled through so that each bit is exposed to the programmer unit forverification or change. After a complete cycle through the shift register (16) the programis fed back to the memory (18) where it is used to control the transfer function of thehearing assisting device. By use of this circular shift register only two connections (12,14)to the programmer unit are required, thereby minimising the mechanical size of theconnector needed to connect the programmer unit to the hearing assisting device, whichmay be an in the ear device. A low voltage version of the interface system uses currentsources and a high voltage version of the interface system, such as used for a remotecontroller, uses impedances and a voltage source .
