4.5

Status register

The status register contains a number of status and control bits, as shown in Table 6, that

can be read or set (as appropriate) by specific instructions.

4.5.1

WIP bit

The write in progress (WIP) bit indicates whether the memory is busy with a write status

4.5.2

WEL bit

The write enable latch (WEL) bit indicates the status of the internal write enable latch.

4.5.3

BP1, BP0 bits

The block protect (BP1, BP0) bits are non-volatile. They define the size of the area to be

software protected against program and erase instructions.

4.5.4

SRWD bit

The status register write disable (SRWD) bit is operated in conjunction with the Write

Protect (W) signal. The status register write disable (SRWD) bit and Write Protect (W) signal

allow the device to be put in the hardware protected mode. In this mode, the non-volatile bits

of the status register (SRWD, BP1, BP0) become read-only bits.
