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
Figure 8.7 Data# Polling Algorithm
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.
During an Embedded Program or Erase algorithm operation, two immediate consecutive read cy-
cles to any address cause DQ6 to toggle. When the operation is complete, DQ6 stops toggling.
For asynchronous mode, either OE# or CE# can be used to control the read cycles. For synchro-
nous mode, the rising edge of ADV# is used or the rising edge of clock while ADV# is Low.
