Autoselect Mode
The autoselect mode provides manufacturer and device
identification, and sector protection verification, through
identifier codes output on I/O7 - I/O0. 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 VID (9.5V to 11.5 V) on address pinA9. Address pins
A6, A1, and A0 must be as shown in Autoselect Codes (High
Voltage Method) table. In addition, when verifying sector
A29010B Series
protection, the sector address must appear on the appropriate
highest order address bits. Refer to the corresponding Sector
Address Tables. The Command Definitions table 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/O7 -
I/O0.To access the autoselect codes in-system, the host system
can issue the autoselect command via the command register,
as shown in the Command Definitions table. This method does
not require VID. See "Command Definitions" for details on using
the autoselect mode.
