Hi

I have a question about ARM architecture

why there is two registers to enable/disable interrupts? ISER and ICER

Is it not possible to set/reset the same register for enable/disabling the interrupts?

thank you

Hi Cyrus,

this question is related to ARM Cortex processor rather that the whole NXP MCU. For instance you should identify which ARM core are you using. For details about ARM cores you may contact ARM or check their infocenter.

4.2.3. Interrupt Clear-enable Register

4.2.2. Interrupt Set-enable Registers

Carlos
