To differentiate the sockets in the pin diagram, all socket-specific pins have either A_ or B_ prepended to the pin names indi-
cated. For example, A_A[25:0] and B_A[25:0] are the independent address buses to the sockets.
When a socket is configured as an ATA drive interface, socket interface pin functions change. See
