6.5.7 Interrupt Clear-Pending Register 0 register (ICPR0 - 0xE000 E280)
The ICPR0 register allows clearing 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 cleared via the ICPR1 register (Section 6.5.8
). Setting the pending
state of interrupts is done through the ISPR0 and ISPR1 registers (Section 6.5.5
and
Section 6.5.6
).

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