Autoselect Mode
The autoselect mode provides manufacturer and device
identification, and sector protection verification, through
identifier codes output on I/O
7
- I/O
0
. This mode is primarily
intended for programming equipment to automatically match
a device to be programmed 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 V
ID
(8.5V to 12.5 V) on address pin A9. Address
pins A6, A1, and A0 must be as shown in Table 5. In
addition, when verifying sector protection, the sector address
must appear on the appropriate highest order address bits.
(see Table 3-4). Table 5 shows the remaining address bits
that are don't care. When all necessary bits have been set as
required, the programming equipment may then read the
corresponding identifier code on I/O
7
- I/O
0
.
To access the autoselect codes in-system, the host system
can issue the autoselect command via the command
register, as shown in Table 12. This method does not require
V
ID
. Refer to the Autoselect Command Sequence section for
more information.
