When the WSM is active, SR[7] will indicate the status of the WSM; the remaining bits
in the Status Register indicate whether the WSM was successful in performing the
preferred operation See
Clear Status Register
The WSM can set Status Register bits 1 through 7 and can clear bits 2, 6, and 7, but
the WSM cannot clear Status Register bits 1, 3, 4 or 5. Because bits 1, 3, 4, and 5
indicate various error conditions, these bits can be cleared only through the Clear
Status Register (0x50) command. By allowing the system software to control the
resetting of these bits, several operations may be performed (such as cumulatively
programming several addresses or erasing multiple blocks in sequence) before reading
the Status Register to determine if an error occurred during that series. Clear the
Status Register before beginning another command or sequence. The Read Array
command must be issued before data can be read from the memory array. Resetting
the device also clears the Status Register.
Program Mode
Programming is executed using a two-write cycle sequence. The Program Setup
command (0x40) is issued to the CUI, followed by a second write that specifies the
address and data to be programmed. The WSM will execute a sequence of internally
timed events to program preferred bits of the addressed location, then verify the bits
are sufficiently programmed. Programming the memory results in specific bits within an
address location being changed to a “0.” If users attempt to program “1”s, the memory
cell contents do not change and no error occurs.
The Status Register indicates programming status. While the program sequence
executes, status bit 7 is “0.” The Status Register can be polled by toggling either CE#
or OE#. While programming, the only valid commands are Read Status Register,
Program Suspend, and Program Resume.
When programming is complete, the program-status bits must be checked. If the
programming operation was unsuccessful, SR[4] is set to indicate a program failure. If
SR[3] is set, then V
the program command. If SR[1] is set, a program operation was attempted on a locked
block and the operation was aborted.
The Status Register should be cleared before attempting the next operation. Any CUI
instruction can follow after programming is completed; however, to prevent inadvertent
Status Register reads, be sure to reset the CUI to read-array mode.
