4.8 PCI Express
4.8.1 PCI Express x1
There are four one-lane PCI Express ports available in the PCH NM10. The
ports are compliant to the PCI Express 1.0 specification running at 2.5 Gb/s.
Only two PCIe x1 Ports, 0~1, are left on the CT-CCV6X COM
™
Express
connector since Port 2 is occupied by GbE and Port 3 is occupied by USB3.0.

4.9 High Definition Audio
The High Definition Audio (HDA) controller is integrated with PCH NM10. It
communicates with the external codec(s) over the Intel
®
High Definition Audio
serial link. The controller consists of a set of DMA engines that are used to
move samples of digitally encoded data between system memory and an
external codec(s). The PCH implements a single Serial Data Output signal
(HDA_SDOUT) that is connected to all external codecs. Three Serial Digital
Input signals (HDA_SDIN[2:0]) provided by the PCH support up to three
codecs.
Signal I/O Description
AC/HDA_RST# O
Reset output to CODEC, active low
AC/HDA_SYNC O
Sample-synchronization signal to the CODEC(s)
AC/HDA_BITCLK O
Serial data clock generated by the external
CODEC(s)
AC/HDA_SDOUT O
Serial TDM data output to the CODEC
AC/HDA_SDIN[2:0] I/O
Serial TDM data input from up to 3 CODECs
