Refer to the AC Characteristics tables for RESET#
parameters and to
Figure 15 on page 29
for the tim-
ing diagram.
Output Disable Mode
When the OE# input is at V
IH
, output from the de-
vice is disabled. The output pins are placed in the
high impedance state.

Am29SL400CB Bottom Boot Block Sector Address Table
Note for Tables 2 and 3:
Address range is A17: A-1 in byte mode and A17:A0 in word mode. See “Word/Byte Configuration”
section for more information.
Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. This
mode is primarily intended for programming equip-
ment to automatically match a device to be pro-
grammed with its corresponding programming
algorithm. However, the autoselect codes can also be
accessed in-system through the command register.
When using programming equipment, the autoselect
mode requires VID on address pin A9. Address pins
A6, A1, and A0 must be as shown in
Table 4 on
page 12
. In addition, when verifying sector protec-
tion, the sector address must appear on the appro-
