• 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.
