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 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
The status 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, 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, Program or Erase instruction is accepted.
BP2, BP1, BP0 bits
The Block Protect bits (BP2, BP1, BP0) are non-volatile. They define the size of the area to
be software protected against Program and Erase instructions. These bits are written with
the Write Status Register (WRSR) instruction. When one or more of the Block Protect (BP2,
BP1, BP0) bits is set to ‘1’, the relevant memory area (as defined in
protected against Page Program (PP), Page Erase (PE), Sector Erase (SE) and Subsector
Erase (SSE) instructions. The Block Protect (BP2, BP1, BP0) bits can be written provided
that the Hardware Protected mode has not been set. The Bulk Erase (BE) instruction is
executed if, and only if:
SRWD bit
The Status Register Write Disable (SRWD) bit is operated in conjunction with the Write
Protect (W) signal. When the Status Register Write Disable (SRWD) bit is set to ‘1’, and
Write Protect (W) is driven Low, the non-volatile bits of the Status Register (SRWD, BP2,
BP1, BP0) become read-only bits. In such a state, as the Write Status Register (WRSR)
instruction is no longer accepted for execution, the definition of the size of the Write
Protected area cannot be further modified.
