S32K312 SPI EXAMPLE

In the code below, the slave is sending an interrupt signal.

However, there is no separate IRQ in the PIN configuration, and I wonder how the master judges the interrupt signal request signal.

So, if you have a location or function to judge, please let me know.

this example name : Lpspi_FLEXIO_IP_TRANSFER_S32K312

Hi,

if you refer to Lpspi_Ip_UpdateTransferMode function, this does not send any interrupt signal on pin etc. It just updates mode a driver services transfer. For interrupt mode the driver will call peripheral interrupt (if enabled properly) and transferred bytes/words are processed in this interrupt.

BR, Petr

THANKS YOUR ANSWER ABOUT MY QUESTION.

AND.. I HAVE MORE QUESTION ABOUT INTERRUPT..

If I write an interrupt signal with a GPIO pin, can I just recognize it if I input it with LOW, HIGH, and the IP over there is in interrupt mode? Or should I set it up separately?

And if I set the IP setting to folding mode, do I just think of it as continuing to send and receive signals without any other signals? Periodically
