The following are C source code examples of using the unlock bypass entry, program, and exit
functions. Refer to the
Spansion Low Level Driver User’s Guide
(available soon on
www.amd.com
and
www.fujitsu.com
) for general information on Spansion Flash “memory software development
guidelines.
/* Example: Unlock Bypass Entry Command */
*( (UINT16 *)bank_addr + 0x555 ) = 0x00AA; /* write unlock cycle 1 */
*( (UINT16 *)bank_addr + 0x2AA ) = 0x0055; /* write unlock cycle 2 */
*( (UINT16 *)bank_addr + 0x555 ) = 0x0020; /* write unlock bypass command */
/* At this point, programming only takes two write cycles. */
/* Once you enter Unlock Bypass Mode, do a series of like */
/* operations (programming or sector erase) and then exit */
/* Unlock Bypass Mode before beginning a different type of */
/* operations. */
/* Example: Unlock Bypass Program Command */
/* Do while in Unlock Bypass Entry Mode! */
*( (UINT16 *)bank_addr + 0x555 ) = 0x00A0; /* write program setup command */
*( (UINT16 *)pa ) = data; /* write data to be programmed */
/* Poll until done or error. */
/* If done and more to program, */
/* do above two cycles again. */
/* Example: Unlock Bypass Exit Command */
*( (UINT16 *)base_addr + 0x000 ) = 0x0090;
*( (UINT16 *)base_addr + 0x000 ) = 0x0000;
8.5.9
W rite Operation Status
The device provides several bits to determine the status of a program or erase operation. The
following subsections describe the function of DQ1, DQ2, DQ3, DQ5, DQ6, and DQ7.
DQ7: Data# Polling.
The Data# Polling bit, DQ7, indicates to the host system whether an Em-
bedded Program or Erase algorithm is in progress or completed, or whether a bank is in Erase
Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command se-
