Operating Humidity 5 - 95%, non-condensing WATCHDOG TIMER The Watchdog Timer is provided to ensure that standalone systems can recover from catastrophic conditions that cause the CPU to crash. This condition can occur from ex- ternal EMI or a software bug. When the CPU stops working correctly, hardware on the board will either perform a hardware reset (cold boot) or a Non-Maskable Interrupt (NMI) to bring the system back to a known state. Two I/O ports control the Watchdog Timer: 443 (hex) Rea

The E2KEY.OBJ provides two library functions for you to integrate your application 2 with the E KEY function. The read_e2key and write_e2key libraries are written and compiled in C language. To implement them, refer to the functions below: */unsigned int read_e2key(unsigned int address): This function will return the 2 E KEY data to a certain address. The address range is from 0 to 63. Return data is one word, 16 bits. */void write_e2key(unsigned int address, unsigned data): This function will w
