4.2.4. Interrupt Clear-Pending Register

The NVIC_ICPR removes the pending state from interrupts, and shows which interrupts are pending. See the register summary in Table 4.2 for the register attributes.

The bit assignments are:

Table 4.6. NVIC_ICPR bit assignments

Interrupt clear-pending bits.


0 = no effect.

1 = removes pending state from interrupt.


0 = interrupt is not pending.

1 = interrupt is pending.


Writing 1 to an NVIC_ICPR bit does not affect the active state of the corresponding interrupt.
