13 / 194 page  13 FLOPPY DISK CONTROLLER The Floppy Disk Controller (FDC) provides the interface between a host microprocessor and the floppy disk drive. 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 FDC is compatible to the 82077AA using SMSC's proprietary floppy disk controller core. FDC INTERNAL REGISTERS The Floppy Disk Controller contains 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. Table 2 - Status, Data and Control Registers (Shown with base addresses of 3F0 and 370) PRIMARY ADDRESS SECONDARY ADDRESS R/W REGISTER 3F0 3F1 3F2 3F3 3F4 3F4 3F5 3F6 3F7 3F7 370 371 372 373 374 374 375 376 377 377 R R R/W R/W R W R/W R W Status Register A (SRA) Status Register B (SRB) Digital Output Register (DOR) Tape Drive Register (TSR) Main Status Register (MSR) Data Rate Select Register (DSR) Data (FIFO) Reserved Digital Input Register (DIR) Configuration Control Register (CCR) |
