To access the Autoselect codes, the host system must issue the Autoselect command.
The Autoselect command sequence may be written to an address within a bank that is either in the read or
erase-suspend-read mode.
The Autoselect command may not be written while the device is actively programming or erasing.
Autoselect does not support simultaneous operations or burst mode.
The system must write the reset command to return to the read mode (or erase-suspend-read mode if the
bank was previously in Erase Suspend).
See
Table 11.1
for command sequence details.
Software Functions and Sample Code
Notes
1. Any offset within the device works.
2. BA = Bank Address. The bank address is required.
3. base = base address.
The following is a C source code example of using the autoselect function to read the manufacturer ID. Refer
to the
Spansion Low Level Driver User’s Guide
(available on
www.spansion.com
) for general information on
Spansion Flash memory software development guidelines.
