Description: Floppy Disk Hard Sector Data Handler

Features

* o Hard-Sectored Operation - performs all data operations o Single or Double Density Operation- recording code independent o Minifloppy or Standard Floppy compatible o Programmable Sync Byte o Internal Sync Byte Detection and Byte Framing o Fully Double Buffered o Data Overrun/Underrun Detection o Du

Applications

* such as the end of a logical file, the system buffer may contain less than a full sector of data. In this case the processor need supply only this data to the FDC3400. The FDC3400 will then underrun, setting the Write Data Underrun Status line and thereby causing the remainder of the sector to fill
