Need to know how to write Interrupt service routine in cc2650

hi,

I am using cc2650 processor in smart RF06 board and interfacing ADXL362 accelerometer to cc2650 using SPI interface

i want to use interrupt and wanted to know how the interrupt function is written and the steps to write an interrupt service routine   and how to map the ISR to a particular interrupt register in ADXL362

Regards,

Sami
