Bits 31:0 SETENA: Interrupt set-enable bits.
Write:
Read:
If a pending interrupt is enabled, the NVIC activates the interrupt based on its priority. If an
interrupt is not enabled, asserting its interrupt signal changes the interrupt state to pending,
but the NVIC never activates the interrupt, regardless of its priority.
Bits 16 to 31 of the NVIC_ISER7 register are reserved.
Note: The number of interrupts is product-dependent. Refer to reference manual/datasheet of
relevant STM32 product for related information.
