Interrupt for every byte receive from spis

[konsang]

Hi,

Does the SPIS generate interrupt for every byte of data receive ?

What kind of interrupt of event that SPIS will generate for data received ?

Please advise

Hi,

Yes, you can set the MAXRX to 1 and enable the interrupt that can be triggered for ENDRX event. Then you will get an interrupt for every byte received .

Hi, 

I need to read the SPI data for every byte data received before the SS pin is asserted. 

I know to do this, I cannot use the driver because of semaphore safe access. But, I can force to direct access the memory without using the driver.

Can you guide me or show me an example code to do this ?

Thanks.

Br,
