Watch Dog Timer Programming Procedure

•

••

•Power on or reset the system

The initial value of WDT Control Register (D4~D0) is zero, when power is on or reset

the system. The following means the initial value of WDT ( 00000000b ) :

Bit Value Mean

4 0 Select Reset

3 0 Disable watch dog timer

2, 1, 0 0 0 0 Select 64 second

•

••

•Initialize the SQW of RTC (set SQW output period=0.5 second)

To initialize the SQW of RTC processor is to set the SQW signal which is output

period=0.5 second. It offers the basic frequency of the WDT counter.

The following is an example of initializing the SQW signal program in Intel 8086
