6.5.5 Interrupt Set-Pending Register 0 register (ISPR0 - 0xE000 E200)
The ISPR0 register allows setting the pending state of the first 32 peripheral interrupts, or 
for reading the pending state of those interrupts. The remaining interrupts can have their 
pending state set via the ISPR1 register (Section 6.5.6
). Clearing the pending state of 
interrupts is done through the ICPR0 and ICPR1 registers (Section 6.5.7
 and 
Section 6.5.8
).

Bit Name Function
0 ISP_WDT Watchdog Timer Interrupt Pending set.
Write: writing 0 has no effect, writing 1 changes the interrupt state to pending.
Read: 0 indicates that the interrupt is not pending, 1 indicates that the interrupt is pending.
