• SETENA
Interrupt set-enable bits.
Write:
0 = no effect
1 = enable interrupt.
Read:
0 = interrupt disabled
1 = interrupt enabled.
If a pending interrupt is enabled, the NVIC activates the interrupt based on its priority. If an interrupt is not enabled, assert-
ing its interrupt signal changes the interrupt state to pending, but the NVIC never activates the interrupt, regardless of its
priority.
