The Floppy Disk Controller provides the interface between a host processor and one floppy disk drives. It
integrates a controller and a digital data separator with write pre-compensation, data rate selection logic,
microprocessor interface, and a set of registers. The FDC supports data transfer rates of 250 Kbps, 300 Kbps,
500 Kbps, and 1 Mbps. It operates in PC/AT mode and supports 3-mode type drives.
The FDC configuration is handled by software and a set of Configuration registers. Status, Data, and
Control registers facilitate the interface between the host microprocessor and the disk drive, providing
information about the condition and/or state of the FDC. These configuration registers can select the data rate,
enable interrupts, drives, and DMA modes, and indicate errors in the data or operation of the FDC/FDD. The
controller manages data transfers using a set of data transfer and control commands. These commands are
handled in three phases: Command, Execution, and Result. Not all commands utilize all these three phases.
