6.4.2 GPIs
The GPI signals are routed to the feature connector (X38) described in section 6.13.
6.4.3 Power Loss Control
The cBC has full control of the power-up of the SBC, therefore can be used to specify the behavior of the system after an AC power loss
condition. Supported modes are “Always On”, “Remain Off” and “Last State”.
6.4.4 Board Information
The cBC provides a rich data-set of manufacturing and board information such as serial number, EAN number, hardware and firmware revisions,
and so on. It also keeps track of dynamically changing data like runtime meter and boot counter.
6.5 LPC Super I/O Device
The conga-IA3 has an onboard Super I/O controller that provides additional interfaces such as two serial interfaces, optional ccTALK, GPOs,
4-wire CPU and system fans. The Winbond W83627DHG Super I/O controller is connected to the LPC Bus of the Intel
®
SoC.
6.5.1 Serial Ports (COM)
The Super IO controller on the conga-IA3 provides two fully featured RS-232 compliant UART interfaces (COM 0 and 1). The COM 1 interface
can be optionally used as ccTALK compliant interface. The COM ports can drive up to 115 kbit/s at a maximum cable length of 15 m.
