At this point, a Read Array command can be written
to the command register to read data from blocks
other than that which is suspended
. The only
other valid commands at this time are Read Status
Register (70H) and Erase Resume (D0H), at which
time the WSM will continue with the erase
sequence. The erase suspend status and WSM
status bits of the status register will be cleared.
After the Erase Resume command is written to it,
the 28F001BX automatically outputs status register
data when read (see Figure 10, 28F001BX Erase
Suspend/ Resume Flowchart).

The V

status bit, unlike an A/D converter, does not
provide continuous indication of V
PP
level. The WSM
interrogates the V
PP
level only after the Program or
Erase command sequences have been entered and
informs the system if V
PP
has not been switched on.
The V
PP
status bit is not guaranteed to report
accurate feedback between V
PPL
