* After completing the data transfer, if further clocks are applied with CS low, the A/D Converter will output LSB
first data, followed by zeros indefinitely. See Figure 6-3 below.
** TDATA: during this time, the bias current and the comparator power down while the reference input becomes
a high-impedance node, leaving the CLK running to clock out the LSB-first data or zeros.
When operating in Single-ended mode, the sign bit will always be transmitted as a ‘0’.
