ATAIF_SD - Parallel ATA Disk Host Software Driver

ATAIF_SD.PNG

The ATAIF_SD is a complete software set for handling ATAIF - the Parallel ATA disk host controller. The ATAIF_SD provides low level operations between storage media, such as Hard Disk Drives and Compact Flash cards.

The driver supplements ATAIF controller with software elements enabling smooth integration of the controller in a target application. It allows the user to easily access high capacity storage media without detailed knowledge of controller interface. The support for two channels (master and slave) makes operations on two drives significantly easier.

Transfer operations can be executed in PIO, MDMA or Ultra- ATA modes. All operations can be performed using transaction level functions (consistent with eCos OS driver model) or by simple-to-use API. The driver supports both ATA device and DMA controller interrupts.
