Full Status Check
By performing full status check, it is possible to know the execu-
tion results of erase and program operations. Figure 101 shows a
full status check flowchart and the action to be taken when each
error occurs.
Fig. 101 Full status check flowchart and remedial procedure for errors
Ready/Busy (RY/BY) Pin
The RY/BY pin is an output pin (N-channel open drain output)
which, such as the sequencer status (SR7), indicates the operat-
ing status of the flash memory. It is

level (busy) during program
or erase operation and becomes the high impedance state (ready)
when these operations end. The RY/BY pin requires an external
pull-up operation.
