Memory Map and Registers
Addresses: GPIOA_IPOLR – F140h base + 6h offset = F146h
9.2.8 GPIO Interrupt Pending Register (GPIOx_IPR)
This read-only register is used to record any incoming interrupts. The user can read this
register to determine which pin has caused the interrupt. This register can be cleared by
writing ones into the GPIO Interrupt Edge Sensitive register if the interrupt is caused by a
pin, or by writing zeros into the GPIO Interrupt Assert register if the interrupt is caused
by software.
Addresses: GPIOA_IPR – F140h base + 7h offset = F147h
