14 Interfaces
3.17 LPC Debug
A 40-pin, front flip, DB40 connector allows access to debug and update the BIOS, BMC, and OS
code on the module. (Refer to “Debug (DB40)” on page 21.)
3.18 SMARC Interface Signals
Table 3-3 provides the pin signals for the SMARC P-S connector. Refer to the SMARC specifica-
tion at
http://www.sget.org/standards/smarc.html for definitions of the SMARC signals.
