7.2.5

Watchdog raw interrupt status register WDT_RIS

The WDTRIS register is the raw interrupt status register. This value is ANDed with the

interrupt enable bit from the control register to create the masked interrupt, which is passed

to the interrupt output pin.

Table 36 shows the bit assignment of the WDTRIS register.

7.2.6

Watchdog masked interrupt status register WDT_MIS

The WDT_MIS register is the masked interrupt status register. This value is the logical AND

of the raw interrupt status with the timer interrupt enable bit from the control register, and is

the same value which is passed to the interrupt output pin. This register is read-only, and all

bits are cleared by a reset.
