Description

The floppy disk controller (FDC) of the W83627DHG integrates all of the logic required for floppy disk control. The FDC implements a FIFO which provides better system performance in multi-master systems, and the digital data separator supports data rates up to 2 M bits/sec.

The FDC includes the following blocks: Precompensation, Data Rate Selection, Digital Data Separator, FIFO, and FDC Core. The rest of this section discusses these blocks through the following topics: FIFO, Data Separator, Write Precompensation, Perpendicular Recording mode, FDC core, FDC commands, and FDC registers.
