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.  
/* Here is an example of Autoselect mode (getting manufacturer ID) */  
/* Define UINT16 example: typedef unsigned short UINT16; */  
UINT16 manuf_id;  
/* Auto Select Entry */  
*( (UINT16 *)base_addr + 0x555 ) = 0x00AA; /* write unlock cycle 1 */  
*( (UINT16 *)base_addr + 0x2AA ) = 0x0055; /* write unlock cycle 2 */  
*( (UINT16 *)base_addr + 0x555 ) = 0x0090; /* write autoselect command */  
/* multiple reads can be performed after entry */  
manuf_id = *( (UINT16 *)base_addr + 0x000 ); /* read manuf. id */  
/* Autoselect exit */  
*( (UINT16 *)base_addr + 0x000 ) = 0x00F0; /* exit autoselect (write reset command) */
