SRDY control through the external pin
D0
SRDYB : data transfer start ready.
0
Transfer allowed.
1
Transfer not allowed.
q In the case of data control through the register, the
SDRYB input pin must be always set at “H”.
For the control through the register, the SRDY register
must be controlled line by line.
