AN-764 Application Note A FLOPPY DISK CONTROLLER USING THE MC6852 SSDA AND OTHER M6800 MICROPROCESSOR FAMILY PARTS Prepared by: Larry A. Parker Semiconductor Systems Engineering This application note describes a floppy disk controller based on the M6800 family of parts. It uses the Synchronous Serial Data Adapter (SSDA) as the primary data interface with the MPU and does not require DMA for transfer of data to and from memory. A Peripheral Interface Adapter (PIA) controls all non-date related operations in the controller (including seek, drive selection, etc.). MOTOROLA SelJ'Jiconducf:or Producf:s Inc. ©MOTOROLA INC.
