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.
