SPIS3 on NRF52840

[Ray Ma]

I just found out there is no SPI slave support for SPI3 on NRF52840, but the memory map shows a SPI master for SPI3 though. Is it possible to enable SPI slave on SPI3? We are on nRF5_SDK_16.0.0_98a08e2.

Hi Ray

The nRF52840 has four SPI master instances, and three SPI slave instances, meaning that there is no SPIS3 instance. The SPI slave instances are SPI0, SPI1, and SPI2.

Best regards,

Simon
