Write in progress bit
The write in progress (WIP) bit is a volatile read-only bit that indicates whether the
memory is busy with a WRITE, a PROGRAM, or ERASE cycle. When the WIP bit is set to
1, a cycle is in progress; when the WIP bit is set to 0, a cycle is not in progress. WIP is set
and reset automatically by the internal logic of the device.
The write enable latch (WEL) bit is a volatile read-only bit that indicates the status of
the internal write enable latch. When the WEL bit is set to 1, the internal write enable
latch is set; when the WEL bit is set to 0, the internal write enable latch is reset and no
WRITE , PROGRAM, or ERASE command is accepted. The WEL bit is set and reset by
specific commands.
