Table 17. Status Register Bits
(1)
Note: 1. Logic level '1' is High, '0' is Low. -0-1-0-0-0-1-1-1-0- represent bit value in successive Read operations.
2. In case of double word program DQ7 refers to the last word input.

Indicates the P/E.C. status, check
during Program or Erase, and on
completion before checking bits DQ5
for Program or Erase Success.

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.
