Creating Two SPI instances for same slave

[Thangaraj]

We are using NRF52832, SDK 11.0.0.2 alpha, S132 soft Device ,I need some clarifications on using SPI,

1. In nrf52832 SPI Master driver is it possible to create two SPI instances for the same slave device.
2. If Yes is it possible to configure the instance as one for DMA transactions(USE_EASY_DMA==1) and the other for normal SPI transactions(USE_EASY_DMA==0).

Can you please explain, what these lines will do ?

NRF_SPI1->PSEL.MISO = (SPI_PSEL_MISO_PSELMISO_Disconnected << SPI_PSEL_MISO_PSELMISO_Pos); NRF_SPI1->PSEL.MOSI = (SPI_PSEL_MOSI_PSELMOSI_Disconnected << SPI_PSEL_MOSI_PSELMOSI_Pos); NRF_SPI1->PSEL.SCK = (SPI_PSEL_SCK_PSELSCK_Disconnected << SPI_PSEL_SCK_PSELSCK_Pos);
