Toggle Bit ( DQ
6
)
An alternative means for determining the Write operation
status is by monitoring the Toggle Bit, DQ
6
. During a
Write operation, consecutive attempts to read data from
the device will result in DQ
6
toggling between logic 0
(low) and logic 1 (high). When the Write cycle is com-
pleted, the toggling will stop. The device is then ready for
the next operation. See Figure 12 for Toggle Bit timing
waveforms.
Successive Reads
An Alternative means for determining an end of a write
operation is by reading the same address for two con-
secutive data matches.
Product Identification
The Product Identification mode identifies the device as
SST28SF040A/28VF040A and the manufacturer as
SST. This mode may be accessed by hardware and
software operations. The hardware operation is typically
used by an external programmer to identify the correct
algorithm for the SST28SF040A/28VF040A. Users may
wish to use the software operation to identify the device
(i.e., using the device code). For details see Table 2 for
the hardware operation and Figure 18 for the software
operation. The manufacturer and device codes are the
same for both operations.
