’1’
Erase Complete or erase
block in Erase Suspend
Indicates the P/E.C. status, check during
Program or Erase, and on completion
before checking bits DQ5 for Program or
Erase Success.
’0’
Erase On-going

’-1-0-1-0-1-0-1-’
Erase or Program On-going
Successive reads output complementary
data on DQ6 while Programming or Erase
operations are on-going. DQ6 remains at
constant level when P/E.C. operations are
completed or Erase Suspend is
acknowledged.

Error Bit
’1’
Program or Erase Error
This bit is set to ’1’ in the case of
Programming or Erase failure.

Erase
Time Bit
’1’
Erase Timeout Period Expired
P/E.C. Erase operation has started. Only
possible command entry is Erase Suspend
(ES).
’0’
Erase Timeout Period
On-going
An additional block to be erased in parallel
can be entered to the P/E.C.
