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.
