說明

The TL16PC564B/BLV is designed to provide all the functions necessary for a Personal Computer Memory Card International Association (PCMCIA) universal asynchronous receiver transmitter (UART) subsystem interface. This interface provides a serial-to-parallel conversion for data to and from a modem coder-decoder/digital signal processor (CODEC/DSP) function to a PCMCIA parallel data-port format. A computer central processing unit (CPU), through a PCMCIA host controller, can read the status of the asynchronous communications element (ACE) interface at any point in the operation. Reported status information includes the type of transfer operation in process, the status of the operation, and any error conditions encountered.
