SATA
A Marvell 88SE9235 PCIe to SATA controller provides two Gen2 SATA backplane
ports on the PPC11A. The device is
connected to the processor via a PCIe switch.
Both SATA ports (SATA0 and SATA1) are connected to the P0 connector. The two
SATA ports are available with options PPC11A-xxxx3xxx, PC11A-xxxx4xxx,
PC11A-xxxx5xxx and PPC11A-xxxx8xxx (see the

GPIO
The PPC11A supports up to 19 GPIO lines, each with interrupt generation
capabilities. They are all 3.3 V single-ended signals with 5 V tolerance.
Up to 19 lines are controlled by the FPGA and can be configured as inputs, with the
ability to generate level- or edge-triggered interrupts or outputs, with totem-pole or
open-drain drivers.
The GPIO signals are intended only to be used by Abaco software drivers. See the
relevant software manual for details.
