WDT Run/Stop Control

13.3.2  

WDT starts counting when a value other than 0b1010 is written to WDTRUN[3:0]/WDT_CTL register and stops 
when 0b1010 is written.
At initial reset, WDTRUN[3:0] is set to 0b1010 to stop the watchdog timer.
Since an NMI or reset may be generated immediately after running depending on the counter value, WDT should 
also be reset concurrently (before running the watchdog timer), as explained in the following section.

WDT Reset

13.3.3  

To reset WDT, write 1 to WDTRST/WDT_CTL register.
A location should be provided for periodically processing the routine for resetting WDT before an NMI or reset is 
generated when using WDT. Process this routine within 131,072/f

OSC1A

 second (4 seconds when f

OSC1A

 = 32.768 

kHz) cycle.
After resetting, WDT starts counting with a new NMI/Reset generation cycle.
If WDT is not reset within the NMI/Reset generation cycle for any reason, the CPU is switched to interrupt pro-
cessing by NMI or reset, the interrupt vector is read out, and the interrupt handler routine is executed. The reset and 
NMI vector addresses are TTBR + 0x0 and TTBR + 0x08.

If the counter overflows and generates an NMI without WDT being reset, WDTST/WDT_ST register is set to 1. 
This bit is provided to confirm that WDT was the source of the NMI. The WDTST set to 1 is cleared to 0 by reset-
ting WDT.

Operations in halT and SleeP Modes

13.3.4  

halT mode

 

The WDT module operates in HALT mode, as the clock is supplied. HALT mode is therefore cleared by an NMI or 
reset if it continues for more than the NMI/reset generation cycle. To disable WDT while in HALT mode, stop WDT 
by writing 0b1010 to WDTRUN[3:0]/WDT_CTL register before executing the 

halt

 instruction. Reset WDT before 

resuming operations after HALT mode is cleared.

SleeP mode

 

The clock supplied from the CLG module is stopped in SLEEP mode, which also stops WDT. To prevent generation 
of an unnecessary NMI or reset after clearing SLEEP mode, reset WDT before executing the 

slp

 instruction. WDT 

should also be stopped as required using WDTRUN[3:0].
