FLOPPY DISK CONTROLLER
The Floppy Disk Controller (FDC) provides the
interface between a host microprocessor and
the floppy disk drives. The FDC integrates the
functions of the Formatter/Controller, Digital
Data Separator, Write Precompensation and
Data Rate Selection logic for an IBM XT/AT
compatible FDC. The true CMOS 765B core
guarantees 100% IBM PC XT/AT compatibility
in addition to providing data overflow and
underflow protection.
The FDC37C665IR is compatible to the
82077AA using SMSC's proprietary floppy disk
controller core.
FLOPPY DISK CONTROLLER INTERNAL
REGISTERS
The Floppy Disk Controller contain eight internal
registers which facilitate the interfacing between
the host microprocessor and the disk drive.
Table 2 shows the addresses required to access
these registers. Registers other than the ones
shown are not supported. The rest of the
description assumes that the primary addresses
have been selected.
