Description

Write or Erase

Controller(11)

• 1=Ready

• 0=Busy

Indicates whether one of the following operation is in

progress:

• Write Status Register

• Write NVCR

• Write Bytes

• Erase

Erase suspend

• 1=In effect

• 0=Not in effect

Indicates whether an Erase operation has been or is going

to be suspended.

Note: Status bits are reset automatically

Erase

• 1=Failure or protection

error

• 0=Clear

Indicates whether an Erase operation has succeeded or

failed.

Write

• 1=Failure or protection

error

• 0=Clear

Indicates whether a Write Bytes operation has succeeded or

failed; also an attempt to write a 0 to a 1 when VPP = VPPH

and the data pattern is a multiple of 64 bits.

Reserved

Write suspend

• 1=In effect

• 0=Not in effect

Indicates whether a Write Bytes operation has been or will

be suspended.

Protection

• 1=Failure or protection

error

• 0=Clear

Indicates whether an Erase or Write Bytes operation has

attempted to modify the protected array sector.

Addressing

• 1=4-bytes addressing

• 0=3-bytes addressing

Indicates the addressing mode used.

1.6.2.1. Read Flag Status Register Operation(70h)

The Read flag status register can be read continuously and at any time, including

during a write or erase operation. You must read the Read flag status register every

time a write or erase command is issued.
