RTC (Real Time Clock)
An AT compatible date/time clock is located within the chipset. The device also contains a CMOS static
RAM, compatible with that in standard ATs. System configuration data is normally stored in the clock chip's
CMOS RAM in a manner consistent with the convention used in other AT compatible computers.
The battery-backed clock can be set by using the DIGITAL-LOGIC AG SETUP at boot-time.
4.4.4
Watchdog
The watchdog timer detects a system crash and performs a hardware reset. After power up, the watchdog is
always disabled as the BIOS does not send strobes to the watchdog. In case that the user wants to take ad-
vantage of the watchdog, the application must produce a strobe at least every 800 ms. If no strobe occures
within the 800 ms, the watchdog resets the system.
Please refer to the
chapter 12.
The watchdog feature is integrated in the INT15 function.
There are also some programming examples available:
