4.6 ATA Connector P8

Table 10 shows the pinout for P8, a 40-pin connector that interfaces with a standard ATA cable.

Note: This is for ATA use only. SP1, 2, and 3 should be bridged with solder to connect the appro-

priate pull-up/down resistors required for ATA. An 80-pin cable is required for UDMA transfer

modes and recommended for all transfer modes.
