6.4
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
Figure 11
.
Table 7.
The status and control bits of the Status Register are as follows:
6.4.1
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.
6.4.2
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.
6.4.3
BP2, BP1, BP0 bits
The Block Protect (BP2, BP1, BP0) bits 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
Table 3
) becomes
protected against Page Program (PP) and Sector Erase (SE) 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, all Block Protect (BP2,
BP1, BP0) bits are 0.
