If enabled, the processor can implement only bits[7:n] of each field, bits[n-x:0] read as zero and ignore writes. The values of n and x are implementation defined.</SPAN></P> <P><A href="https://developer.arm.com/documentation/dui0646/c/Cortex-M7-Peripherals/Nested-Vectored-Interrupt-Controller/Interrupt-Priority-Registers" target="_blank">https://developer.arm.com/documentation/dui0646/c/Cortex-M7-Peripherals/Nested-Vectored-Interrupt-Controller/Interrupt-Priority-Registers</A></P> <P>Best Regards,<BR />Robin<BR />-------------------------------------------------------------------------------<BR />Note:<BR />- If this post answers your question, please click the "ACCEPT AS SOLUTION" button.
