  Watchdog Timer (WDT) 

5.13

5.13.1  Overview 

The  purpose  of Watchdog  Timer  (WDT)  is  to perform  a  system  reset  when  system  runs  into  an 
unknown  state.  This  prevents  system  from  hanging  for  an  infinite  period  of  time.  Besides,  this 
Watchdog Timer supports the function to wake-up system from Idle/Power-down mode. 

5.13.2  Features 

 

18-bit free running up counter for WDT time-out interval 

 

Selectable time-out interval (2

4

 ~ 2

18

) and the time-out interval is 0.48828125 ms ~ 8 s if 

WDT_CLK = 32.768 kHz 

 

System kept in reset state for a period of (1 / WDT_CLK) * 63 

 

Supports selectable WDT reset delay period, including 1026

、

130

、

18 or 3 WDT_CLK reset 

delay period 

 

Supports to force WDT enabled after chip powered on or reset by setting WDTON in 
PWRON register 

 

Supports WDT time-out wake-up function only if WDT clock source is selected as 32 kHz

Note1: 

WDT resets CPU and lasts 63 WDT_CLK.

 

Note2: 

If user intends to use WDT to wake-up Idle/Power-down mode, it is recommended that  

CPU clock source is set the same as WDT clock source before CPU enters Power-Down mode. 

Note3: 

The WDT reset delay period can be selected as 3/18/130/1026 WDT_CLK. 

5.13.4  Basic Configuration 

The WDT clock control and block diagram are shown as follows.
