The IRQ numbers for the watchdog timers are listed in the System Interrupts chapter. For I/O signals, refer to the end of this chapter.

Note: All of these signals are outputs from the watchdog timer. The system interrupts are level sensitive, active-High.

Table 1. Signals Generated by the SWDT Timer
Description	Window Modes		Generic Mode	System Signal
Description	Basic	Q&A	Generic Mode	Name	Potential Destination
Main interrupt	Active-High interrupt output asserted when an interrupt bit in the Enable_and_Status register is set and not masked.		Enable and status for the interrupts (e.g., G_CSR ).	Active-High: SWDT_INT	IRQ I/O
Main interrupt	Applicable bits: [WINT], [WRP].		[GWEN], [GWS].	Active-High: SWDT_INT	IRQ I/O
Reset to I/O signal to MIO/EMIO	Asserted after a bad event (or when the fail counter overflows, if enabled). The controller auto disables itself (clears the [WEN] bit) and waits to receive a reset.		Asserts on second expiration of the timeout counter.	Active-High: SWDT_RST	I/O
Error signal assertion for PSM			Asserts on second expiration of the timeout counter.	SWDT_ERROR	System error I/O
Pending interrupt	Asserted after a bad event. The controller auto disables itself (clears the [WEN] bit) and waits to receive a reset.		Asserts on the second window timeout.	Active-High: SWDT_RST_PEND	IRQ I/O
Generic window 0 indicator	N/A		Generic timer window 0 active.	Active-High: SWDT_GWS0	IRQ I/O
Generic window 1 indicator	N/A		Generic timer window 1 active.	Active-High: SWDT_GWS1	IRQ I/O
