10 / 30 page DQ Name Logic Level Definition Note 7 Data Polling ’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 DQ Program Complete or data of non erase block during Erase Suspend DQ Program On-going 6 Toggle Bit ’-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. DQ Program Complete ’-1-1-1-1-1-1-1-’ Erase Complete or Erase Suspend on currently addressed block 5 Error Bit ’1’ Program or Erase Error This bit is set to ’1’ in the case of Programming or Erase failure. ’0’ Program or Erase On-going 4 Reserved 3 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. 2 Toggle Bit ’-1-0-1-0-1-0-1-’ Chip Erase, Erase or Erase Suspend on the currently addressed block. Erase Error due to the currently addressed block (when DQ5 = ’1’). Indicates the erase status and allows to identify the erased block 1 Program on-going, Erase on-going on another block or Erase Complete DQ Erase Suspend read on non Erase Suspend block 1 Reserved 0 Reserved Notes: Logic level ’1’ is High, ’0’ is Low. -0-1-0-0-0-1-1-1-0- represent bit value in successive Read operations. Table 9. Status Register Bits Toggle Bit (DQ6). When Programming or Erasing operations are in progress, successive attempts to read DQ6 will output complementarydata. DQ6 will toggle following toggling of either G, or E when G is low. The operation is completed when two suc- cessive reads yield the same output data. The next read will output the bit last programmed or a ’1’ after erasing. The toggle bit DQ6 is valid only during P/E.C. operations, that is after the fourth W pulse for programming or after the sixth W pulse for Erase. If the blocks selected for erasure are pro- tected, DQ6 will toggle for about 100 µs and then return back to Read. DQ6 will be set to ’1’ if a Read operationis attemptedon an Erase Suspendblock. When erase is suspended DQ6 will toggle during programming operations in a block different to the block in Erase Suspend. Either E or G toggling will cause DQ6 to toggle. See Figure 12 for Toggle Bit flowchart and Figure 13 for Toggle Bit waveforms. 10/30 M29F100T, M29F100B |
