– This input signal is used to receive 16-bit data.
– The bits are received in order from the MSB (first) to the LSB (last).
– The pin has an internal pullup.
• DOUT – Serial Output Data
– This output signal is used to transmit 16-bit data.
– It is a 3-state output and it is in high impedance mode when CS is high.
– The serial data bits are transmitted in order from the MSB (first) to the LSB (last).
