Status Read
The device automatically implements the execution and verification of the Program and Erase operations.
The Status Read function is used to monitor the Ready/Busy status of the device, determine the result (pass
/fail) of a Program or Erase operation, and determine whether the device is in Protect mode. The device status
is output via the I/O port on the RE clock after a “70h” command input.
The resulting information is outlined in Table 5.

System Design Note: If the RY / BY pin signals from multiple devices are wired together as shown in the
diagram, the Status Read function can be used to determine the status of each individual device.
