CC3301MOD: Facing challenges in the SPI communication between CC3301MOD Ti WiFi and STM32 Microcontroller.

Part Number: CC3301MOD

I implemented 

  1. Enable signal out from STM32 (GPIO) to CC3301MOD for enabling the Ti WiFi chip.
  2. Initialized & Configured SPI with 10mbps speed and 00 mode.  

Confusion is 

  1. I have connected IRQ pin (External IRQ to STM32) to PC2 pin of STM32.
  2. CC33301MOD chip irq pin number is 10. 
  3. I have implemented ISR & isrcallback function in the STM32.
  4. How can I generate the interrupt from CC3301MOD irq pin 10 to STM32 ? your suggetion is highly appreciated.
