Figure 22-19 shows the integration of the watchdog timers in the device.
Table 22-62 through Table 22-64 summarize the integration of the module in the device.
Module Instance | Attributes | ||
Power Domain | Wake-Up Capability | Interconnect | |
WD_TIMER2 | PD_WKUPAON | Yes | L4_WKUP |
Clocks | ||||
Module Instance | Destination Signal Name | Source Signal Name | Source | Description |
WD_TIMER2 | WD_TIMER2_FCLK | WKUPAON_SYS_GFCLK | PRCM | WD_TIMER2 functional clock |
WD_TIMER2 | WD_TIMER2_ICLK | WKUPAON_GICLK | PRCM | WD_TIMER2 interface clock |
Resets | ||||
Module Instance | Destination Signal Name | Source Signal Name | Source | Description |
WD_TIMER2 | WD_TIMER2_RST | WKUPAON_RST | PRM | Reset to WD_TIMER2 |
MPU_WDT_RST | WD_TIMER2_CMDRST | WD_TIMER2 | Reset to MPU |
WD_TIMER2 is reset on power on or after a warm reset before it starts counting.

The “Default Mapping” column in Table 22-64
Watchdog Timer Hardware Requests shows the default mapping of module IRQ
source signals. These IRQ source signals can also be mapped to other lines of
each device Interrupt controller through the IRQ_CROSSBAR module.
For more information about the IRQ_CROSSBAR
module, see IRQ_CROSSBAR Module Functional Description, in Control
Module.
For
more information about the device interrupt controllers, see Interrupt
Controllers.
