Software Functions and Sample Code
Note
1. Any offset within the device works.
2. 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.
/* 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) */
