Read

The read instruction is the only instruction which outputs serial data on the DO pin. When the 17th falling

edge of SK is received , the DO pin will come out of high impedance state and shift out the data from D15 first

in descending order which is located at the address specified in the instruction.

The data in the next address can be read sequentially by continuing to provide clock. The address

automatically cycles to the next higher address after the 16bit data shifted out.

address $00 allowing the read cycle to be continued indefinitely.
