Read Status Register (RDSR) (05h)
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 7.
This Data Sheet may be revised by subsequent versions 2004 Eon Silicon Solution, Inc., www.essi.com.tw
or modifications due to changes in technical specifications.

Table 6. Status Register Bit Locations
Note
: In OTP mode, SRP bit is served as OTP_LOCK bit,
The status and control bits of the Status Register are as follows:
BUSY bit.
The BUSY 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.
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 both of the Block Protect (BP2, BP1, BP0) bits is
