/* Accessing the FDC 765 */
== Accessing the FDC 765 ==
The Main Status Register (Port FB7Eh) signalizes when the FDC is ready to send/receive the next byte through the Data Register.
The Data Register (Port FB7Fh) is used to write Commands and Parameters, to read/write data bytes, and to receive result bytes. These three operations are called Command-, Execution-, and Result-Phase.
