6.5.4 Interrupt Clear Pending Register 0 register
The ICPR0 register allows clearing the pending state of the peripheral interrupts, or for
reading the pending state of those interrupts. Set the pending state of interrupts through
the ISPR0 register (Section 6.5.3
).
The bit description is as follows for all bits in this register:
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.
