Status Register
The Status Register provides information on the current or previous Program or Erase
operation. Different bits in the Status Register convey different information and errors on the
operation.
To read the Status Register the Read Status Register command can be issued. The Status
Register is automatically read after Program, Erase and Program/Erase Resume
commands are issued. The Status Register can be read from any address.
The Status Register bits are summarized in
Status Register bits
. Refer to
Table 8
in
conjunction with the text descriptions below.
5.0.1
Program/Erase Controller status (Bit 7)
The Program/Erase Controller Status bit indicates whether the Program/Erase Controller is
active or inactive. When the Program/Erase Controller Status bit is ‘0’, the Program/Erase
Controller is active; when the bit is ‘1’, the Program/Erase Controller is inactive.
The Program/Erase Controller Status is ‘0’ immediately after a Program/Erase Suspend
command is issued until the Program/Erase Controller pauses. After the Program/Erase
Controller pauses the bit is ‘1’.
During Program and Erase operation the Program/Erase Controller Status bit can be polled
to find the end of the operation. The other bits in the Status Register should not be tested
until the Program/Erase Controller completes the operation and the bit is ‘1’.
After the Program/Erase Controller completes its operation the Erase Status, Program
Status, V
PP
Status and Block Protection Status bits should be tested for errors.
5.0.2
Erase Suspend status (Bit 6)
The Erase Suspend Status bit indicates that an Erase operation has been suspended and is
waiting to be resumed. The Erase Suspend Status should only be considered valid when the
Program/Erase Controller Status bit is ‘1’ (Program/Erase Controller inactive); after a
Program/Erase Suspend command is issued the memory may still complete the operation
rather than entering the Suspend mode.
When the Erase Suspend Status bit is ‘0’ the Program/Erase Controller is active or has
completed its operation; when the bit is ‘1’ a Program/Erase Suspend command has been
issued and the memory is waiting for a Program/Erase Resume command.
When a Program/Erase Resume command is issued the Erase Suspend Status bit returns
to ‘0’.
