SYSTEMS 15 WATCHDOG TIMER The watchdog timer can be used to trigger an interrupt or system reset upon the expiration of a programmed time interval The purpose of this timer is to enable the system to recover from a software or hardware error that causes the system to freeze or get caught up in a software infinite loop The watchdog timer uses I O address range 0x67 Ox6D It uses a 24 bit down counter for the timeout interval with a resolution of 30 5usec The shortest timeout interval is 30 5us and the longest timeout interval is 30 5us x 2 511 sec To use the watchdog timer first make sure it is enabled in the BIOS The default setting is enabled Go to Chipset then South Bridge Configuration and select Watchdog Configuration Set WDT1 to Enabled WDT1 is enabled the steps are as follows First program the desired timeout interval then select the timeout event then enable the timer Once the timer is enabled the software must reset it before it times out or else the timeout event will occur This reset must occur repeatedly until the watchdog timer is disabled The steps to set up and use the watchdog timer are as follows 1 Write the desired time delay into registers is the LSB 2 Select timer reset event using register 0x69 3 Set register 0x68 bit 6 0x40 to enable the timer 4 To retrigger the timer and prevent the selected event from occurring write any val

YSTEMS 9 2 LCD There are two common types of LCD signaling used in embedded computers LVDS and TTL The LCD output on Helix uses the more popular LVDS low voltage differential signaling format If you are planning to use a TTL LCD with Helix you will need to use a small adapter board that converts LVDS to TTL Many such boards are available from suppliers The LCD used with Helix must match the programmed resolution and scan rate in the Helix BIOS These settings can be changed with a software utility provided with the board see below Helix provides 18 bit LVDS output so the LCD selected must work with 18 bit data As opposed to CRTs there is no standard LCD connector type or format Each LCD manufacturer has its own standards and there are also different specifications such as the number of data bits used in the video signal You will need to create your own LCD cable to connect from the LCD connector on Helix to the input connector on your LCD For assistance with signal definitions or wiring requirements contact the LCD maker or Diamond technical support Diamond offers cable no 6981206 with the correct connector type and pinout to match the LCD connector on Helix The other end may need to be changed to work with your LCD Connector J12 is used to connect an LVDS LCD to Helix 1 Ground D3 depending on video chip 2 Ground D3 depending on video chip 3 Scan Direction High R
