Four basic data paths are provided. One provides the timing and control functions for 8-bit I/O cycles that communicate
control/status information with the IDE devices. A second data path provides the timing and control functions for 16-bit and
32-bit I/O cycles that are used to transfer data to/from the IDE drives with the PIO protocol. The third is used to access the
internal Configuration and Bus Master IDE Register set. The fourth data path is used for the bus master data transfer
protocol. A block of logic is used to interface to the PCI bus as well as separate 8-bit from 16/32-bit cycles and provide bus
master support. A separate block of logic is used to control the IDE interface and timing as well as control the packing and
unpacking of the data between the IDE buffer logic and the PCI buffer logic.
