Hi,

CYW20719 has a "spiffy1_int" (SPIFFY 1 Interrupt (Slave)).

What's the function of INT for "Serial Peripheral Interface"?

Best regards.

Hi,

There is little information about this. Would you give more information on this issue? Like:

  • Where is "spiffy1_int" located?
  • What's is the declaration of "spiffy1_int"?

As far as I'm concerned, the SPIFFY is the notion used for Peripheral SPI interfaces. And the function of INT is the function related to interrupt configuration.

Hi,

Serial Peripheral Interface(SPI) usually has CS, SCLK, MOSI and MISO. Few devices have INT.

I guess INT of CYW20719 will output a interrupt signal to the SPI master at the end of SPI operation cycle.

Am I right or wrong?

Best regards.
