AMI BIOS Setup Utility CEM100 AMD G Series APU COM Express Type 2 Basic Module Appendix A Watchdog Timer and GPIO About Watchdog Timer Software stability is major issue in most application Some embedded systems are not watched by human for 24 hours It is usually too slow to wait for someone to reboot when computer hangs The systems need to be able to reset automatically when things go wrong The watchdog timer gives us solution The watchdog timer is a counter that triggers a system reset when it counts down to zero from a preset value The software starts counter with an initial value and must reset it periodically If the counter ever reaches zero which means the software has crashed the system will reboot About GPIO The onboard GPIO general input and output has 8 bits GPIO 3 and GPOO 3 In default all pins are pulled high with 3 3V level according to main power The BIOS default settings are 4 inputs and 4 outputs where all of these pins are set to 1 Use these GPIO signals to control cash drawers and sense warning signals from an Uninterrupted Power System UPS or perform store security control Sample Program Programming sample code from CEM100 FINTEK F75111R INCLUDE FILE Wi include lt stdio h gt include lt conio h gt include lt bios h gt include lt dos h gt define UCHAR unsigned char define UINT unsigned int define SMIOBASE Gem SMIOBA

IHN HINN NB 1 lt IHN Bottom Side 8 Module and Pin Assignments CEM100 AMD G Series APU COM Express Type 2 Basic Module 2 3 Installing Heat spreader For thermal dissipation a heat spreader enables the CEM100 s components to dissipate heat efficiently All heat generating components are thermally conducted to the heat spreader in order to avoid hot spots Follow steps below to install heat spreader 1 There is a protective plastic covering on the thermal pads This must be removed before the heat spreader can be mounted 2 Each heat spreader is designed for a specific CEM module The thermal pads on the heat spreader are designed to make contact with the necessary components on the CEM module When mounting the heat spreader you must make sure that the thermal pads on the heat spreader make complete contact no space between thermal pad and component with the corresponding components on the CEM module This is especially critical for CEM modules that have higher CPU speeds for example 1 0GHz or more to ensure that the heat spreader acts as a proper thermal interface for cooling solutions 3 This CPU module has seven assembly holes for installing heat spreader plate Align and use screws M2 5x16Lx5pcs and M2 5x4Lx2pcs to secure the heat spreader plate to the CEM100 Be careful not to over tighten the screws Screw M2 5 16L 5Spcs eatspreader ko TQ a PA e Screw M2 5 4LX 2pcs Module
