Read operations on memory array

Read operations are performed independently of the state of the software write protect bit (SWP).

After the successful completion of a read operation, the device internal address counter is incremented by one, to

point to the next byte address.

For the read instructions, after each byte read (data out), the device waits for an acknowledgement (data in)

transfer and switches to its Standby mode.
