register.
DMA Acknowledge. An active LOW input used to interface to an external
DMA controller. DMA is enabled only in slave mode. In host mode, pin
should be tied HIGH (logic “1”).
DMA Request. An active LOW output used with an external DMA
controller. nDRQ and nDACK form the handshake for DMA data transfers.
In host mode, pin must be left unconnected.
Read Strobe Input. An active LOW input used with nCS to Read
registers/data memory.
