Hi,

Sorry for the delay because of the labor's day which is the holiday in Norway.

[quote user=""]

1. How to enable interrupt?

2. Do we need to write 1 in ISER (Interrupt Set Enable Register)? to enable interrupt.

[/quote]

For 1. and 2., Set INTEN to enable or disable interrupt in our chip.

[quote user=""]3. Do we need to initialize the service routine of that interrupt?[/quote]

If you develop the ISR, you need to initial and assing interrupt. In our SDK, Master boot record will do that.

[quote user=""]4. How to define/see interrupt priority?[/quote]

[quote user=""]5. How to define interrupt handler?[/quote]

[quote user=""]6. To disable interrupt do we need to set 1 in ICER (Interrupt Clear Enable Register) register?[/quote]

Clear an interrupt by writing 0 to an event register, or disabling an interrupt by the INTENCLR register in our chip. More details are in Interrupts.

[quote user=""]7. Can you provide me the Interrupt vector table?[/quote]

See the example for the Interrupt vector table. It's located at the start of flash memory

[quote user=""]8. What is soft device based and normal interrupts?[/quote]

SoftDevices is a precompiled and linked binary software implementing a wireless protocol developed by Nordic Semiconductor.

I do not know what normal interrupts means. Where do you find it in our documents?

[quote user=""]9. It would be great if you provide me the simplest code to get a better understanding of interrupts.[/quote]

nRF5 SDK v15.3.0: Pin Change Interrupt Example which demonstrates interrupts on PIN_IN change. PIN_OUT is configured as output and toggled in the PIN_IN change interrupt handler.

Best regards,

Amanda
