CC2642R-Q1: DIO config as GPIO and then config as SPI

Part Number: CC2642R-Q1

Hi Team, 

My customer is using CC2642R-Q1 to control a sensor via SPI inferface.

They just found  the sensor extra need one wakeup pin to wake-up CC2642R-Q1 but only DIO_8~DIO_11 can be used for communication.

However,  DIO_8~DIO_11 is reserved for SPI(SCK/MOSI/MISO/CS) in the design.

Current target:

  When CC2642 is sleep, DIO_10 is set as GPIO wakeup pin. Sensor will wake up CC2642 when buffer full.

   When CC2642 is waked- up by DIO_10,  DIO_10 is set as MISO of SPI.CC2642 will begin SPI transaction.

 

Please help to check if the DIO_10 can change function between GPIO and SPI(MISO).

Thanks.
