Data Sheet
Status Register
The software status register provides status on whether the
flash memory array is available for any Read or Write oper-
ation, whether the device is Write enabled, and the state of
the memory Write protection. During an internal Erase or
TABLE 4: S
Busy
The Busy bit determines whether there is an internal Erase
or Program operation in progress. A “1” for the Busy bit indi-
cates the device is busy with an operation in progress. A “0”
indicates the device is ready for the next valid operation.
Write Enable Latch (WEL)
The Write-Enable-Latch bit indicates the status of the inter-
nal memory Write Enable Latch. If the Write-Enable-Latch
bit is set to “1”, it indicates the device is Write enabled. If the
bit is set to “0” (reset), it indicates the device is not Write
enabled and does not accept any memory Write (Program/
Erase) commands. The Write-Enable-Latch bit is automati-
cally reset under the following conditions:
