operation and DQ7 has valid data, the data outputs on DQ6-DQ0 may be still invalid. Valid data on DQ7-D00
appears on successive read cycles.
See the following for more information:
Table 8.9,
Write Operation Status
on page 36
shows the outputs for
Data# Polling on DQ7.
Figure 8.7,
Data# Polling Algorithm,
on page 32
shows the Data# Polling timing
diagram.

Notes
1. VA = Valid address for programming. During a sector erase operation, a valid address is an address within any sector selected for
erasure. During chip erase, a valid address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 =
1
because DQ7 may change simultaneously with DQ5
8.8.2
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete,
or whether the device has entered the Erase Suspend mode.
Toggle Bit I may be read at any address in the same bank, and is valid after the rising edge of the final WE#
pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-
out.
