Read Status Register (RDSR)
The Read Status Register (RDSR) instruction allows the Status Register to be read. The
Status Register may be read at any time, even while a Program, Erase or Write Status
Register cycle is in progress. When one of these cycles is in progress, it is recommended to
check the Write In Progress (WIP) bit before sending a new instruction to the device. It is
also possible to read the Status Register continuously, as shown in
Table 6.
The status and control bits of the Status Register are as follows:
WIP bit
The Write In Progress (WIP) bit indicates whether the memory is busy with a Write Status
Register, Program or Erase cycle. When set to 1, such a cycle is in progress, when reset to
0 no such cycle is in progress.
WEL bit
The Write Enable Latch (WEL) bit indicates the status of the internal Write Enable Latch.
When set to 1 the internal Write Enable Latch is set, when set to 0 the internal Write Enable
Latch is reset and no Write Status Register, Program or Erase instruction is accepted.
