5.1SATA JTAG Interface

The Intel® 31244 PCI-X to Serial ATA Controller JTAG interface is provided to assist on-board testing on one of the four 31244 devices. Table 15 shows the pin assignment of the 10-pin header for the JTAG (J38) on PCI-X to Serial ATA controller (U30).

5.2Intel® 31244 PCI-X to Serial ATA Controller

Each of the 31244 chips transmits and receives commands to one of the four Serial ATA channels. Direct Port Access or DPA mode is hard-wired on each of the SATA controllers. DPA mode allows independent control of the SATA devices, allowing multiple disks to be accessed at the same time. Refer to the Intel® 31244 PCI-X to Serial ATA Controller Developer’s Manual (273603) for more information.
