The single channel audio codec is designed for direct connection of a microphone and speaker. The built-in telecom codec can directly be connected to a DAA and supports high speed modem protocols. The incorporated 10 bit analogue to digital converter and the touch screen interface provides complete control and readout of a connected 4 wire resistive touch screen. The 10 additional general purpose I/O pins provides programmable inputs and/or outputs to the system. The UCB1100 has a serial interface bus (SIB) intended to communicate to the system controller. Both the codec input and output data and the control register data is multiplexed on this SIB interface.
