3.6 ATA Connector P8
Table 3-10 shows the pinout for P8, a 40-pin connector that interfaces with a standard ATA cable.
This is for ATA use only. SP1, 2, and 3 should be bridged with the solder to connect the appropriate
pull-up and pull-down resistors required for ATA. An 80-pin cable is required for UDMA transfer
modes and recommended for all transfer modes.

3.7 U2 - 22v10 Gate Array Logic (GAL)
A standard 22v10 GAL provides a general-purpose “glue logic” on the board. It provides the AND
gate required to combine the PSEN and READ signals, adds memory map support, debug LEDs,
and provides three spare outputs for customer-defined functions.
