The codec has two interface ports: a parallel port for data transfer and a serial port for control. The parallel port is 16 bits wide, and is reserved for moving data between the codec and the host transceiver, such as the TMS320C6XX. Configuration is done via the serial port. A special interface scheme enables multichannel system design. The TLV320AD16 can be powered down via a dedicated terminal or through software control to reduce heat dissipation. Additionally, there is a general-purpose (GP) port consisting of eight output terminals for control of external circuitry.
