I'm using LPC5410x NXP controller, we are implementing SPI FIFO-DMA full duplex mode. As of now we understand that SPI Tx register has 32-bit register(16-bit for control/16-bit for DATA) whereas SPI Rx register 32-bit register dedicated to DATA.
To work in full duplex mode, i configured the control register for MasterTx and its working fine. should i configure the same to SlaveTx??
Whether configure or not we are missing few bytes initially and duplication happening at end.
Please suggest how to handle SlaveTx data
