Status Read
Read (2) command “71H”.
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 Status Read command “70H” or “71H” input.
The resulting information of Status Read (1) command “70H” is outlined in Table 5 below and the resulting
information of Status Read (2) command “71H” is outlined in the explanation for Multi Block Program and Multi
Block Erase toward the end of this document.
