Ready/Busy (RY/BY) pin
The RY/BY pin is an output pin which, like the write state machine (WSM) status (SR7), indicates the
operating status of the flash memory. It is "L" level during the auto write- or the auto erase operation
and becomes to the high-impedance state (ready state) when the operation ends. The RY/BY pin
requires an external pull-up.
