3. Reading (READ)

The READ instruction reads data from a specified address.

After CS has gone high, input an instruction in the order of the start bit, read instruction, and address.

impedance (Hi-Z) to low, which is held until the next rise of SK. 16-bit data starts to be output in

synchronization with the next rise of SK.

3.1 Sequential read

After the 16-bit data at the specified address has been output, inputting SK while CS is high

automatically increments the address, and causes the 16-bit data at the next address to be output

sequentially. The above method makes it possible to read the data in the whole memory space.
