5.3 SATA Interface
Four of the AMD Fusion Control Hub SATA 3.0 channels are routed to the four COM Express SATA channels. The FCH
SATA 0-3 ports map to the COM Express SATA 0-3 pins.
Note: SATA trace lengths on module, which exceed recommended limit for SATA 3.0 traces, and the inclusion of the
COM Express connector reduces signal amplitude and increases jitter. No failures have been seen during functional
testing.
5.3.1 Configuration
The SATA controller is a PCIe bus device. The BIOS allocates the required system resources during the PCIe device
configuration.
5.4 Audio Interface
The AMD Fusion Control Hub supports High Definition Audio (HDA). This HD audio configuration supports three
audio channels. HDA channels 0 – 2 are mapped to COM Express AC/HDA channels 0 – 2.
5.4.1 Configuration
The audio controller is in the AMD FCH. The BIOS allocates the required system resources during configuration.
5.5 LPC Serial IRQ
The LPC serial interrupt request pin (A50) offers a standardized interface to link interrupt request lines to a single
I/O wire.
5.5.1 Configuration
The serial IRQ machine is in “Continuous Mode”.
