Question
I am confused which signals will start the transfer, CASCIN and SCLK or RFS and SCLK?The data will be sent out when which signal is turned low, RFS or DRDY?
Answer
In Slave Mode, the data will begin to clock out on the rising edge of SCLK after RFS goes Low and the data is valid on the falling edge of SCLK.Conditions: DRDY must be valid i.e low, see CASCADING DEVICES if connecting multiple devices.
