4.15.5 Single Device Operation

For applications with a single device or applications with multiple devices where daisy

chaining is not desired, the chain position bits C[6:0] should always be set to 0. As a

by-product of the daisy chaining feature, Read and Write operations experience a 32

SCK cycle latency from SDI to SDO. For more details on daisy-chaining, refer to

Section 4.15.8 on page 29.
