COMPACT FLASH CONTROLLER

5.1 OVERVIEW OF COMPACT FLASH CONTROLLER

A Compact Flash Controller (CFC) connects seamlessly to the AHB Bus as a Bus slave and AHB Master. The
CFC subsystem recognizes AHB Bus transactions that target the compact flash card. The Master Interface
initiates compact flash card requests to the CFC block requester interface. The Slave interface responds to the
requests initiated. To complete the AHB Bus transaction, the CFC drives the appropriate AHB response onto the
AHB Bus.
The CFC can control the Hard Disk and the Compact Flash that can operate in true IDE mode.
