SoftDevice Interrupt Vector Table Offsets

SoftDevice interrupt vector table offsets. The SoftDevice interrupt vector table contains only the addresses of the interrupt handlers required by the SoftDevice. The table is located at the SoftDevice base address. When the SoftDevice is enabled, the application must forward the interrupts corresponding to the defined offsets to the SoftDevice. The address of the interrupt handler is located at the SoftDevice base address plus the offset. More...

Detailed Description

SoftDevice interrupt vector table offsets. The SoftDevice interrupt vector table contains only the addresses of the interrupt handlers required by the SoftDevice. The table is located at the SoftDevice base address. When the SoftDevice is enabled, the application must forward the interrupts corresponding to the defined offsets to the SoftDevice. The address of the interrupt handler is located at the SoftDevice base address plus the offset.

An example of how to forward an interrupt to the SoftDevice is shown below:

SVC_Handler:
  LDR   R0, =NRF_SD_ISR_OFFSET_SVC
  LDR   R1, =SOFTDEVICE_BASE_ADDRESS
  LDR   R1, [R1, R0]
  BX    R1
