Basic Questions

Question

Hello, We are looking into using this chip to transmit UDP packets and I have some basic questions. Do the chip add any information to the UDP packet? For example, the header and checksum of the packet? I looked in the sample code and I couldn’t see how the chip select was being used for reading from the socket. To read, do I follow these instructions: Set the address pins Pull chip select low Enable Read Read data from data pins Disable Read chip select high If that is the case, how do I know when the read data is valid? What about writing to a socket? Set address pins Pull chip select low Set data pins Enable write Disable write Set chip select high If this is the case, how do I know when the data has been written? What about read/writes from a buffer? Do I have to enable chip select and read multiple times?
