READ (READ SEQUENCE)
After CS changes high to low, the op-code and address are sent on SI pin and the data (D7-D0)
read from SO pin.
After 1 byte of data output, internal address register is incremented, and the next byte of data is
outputted. After READ the data in the highest address, the address register rolls over to the lowest
address. After the last bit of the address shift into the register, the input data on SI pin is ignored.
