Bit 31 – NMI: Non-Secure Non-Maskable Interrupt

Non-Secure Non-Maskable Interrupt

This bit enables the non-secure mode of NMI.

The registers whose content is set in non-secure mode by NONSEC.NMI are NMICTRL and NMIFLAG registers.

ValueDescription
0 NMI is secure.
1 NMI is non-secure.

Bits 7:0 – EXTINT[7:0]: Non-Secure External Interrupt

Non-Secure External Interrupt

The bit x of EXTINT enables the non-secure mode of EXTINTx.

The registers whose EXTINT bit or bitfield x is set in non-secure mode by NONSEC.EXTINTx are EVCTRL, ASYNCH, IDEBOUNCEN, NTENCLR, INTENSET, INTFLAG and CONFIG registers.

ValueDescription
0 EXTINTx is secure.
1 EXTINTx is non-secure.
