Interrupt for every byte receive from spis

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

  • Worst case interrupt latency has to include softdevice interrupts. That would put a usable SCK frequency down to somewhere in the single-digit kHz range.

    You rather want to use a maximum size RX buffer for EasyDMA and use the RXD.AMOUNT register to read how many bytes where sent in a frame.
