Device Mode
Description
70
Read Status
Register
Puts the device into the read status register mode, so that reading the device
outputs status register data, regardless of the address presented to the device.
The device automatically enters this mode after program or erase has completed.
This is one of the two commands that is executable while the WSM is operating.
See Section 3.2.3.
50
Clear Status
Register
The WSM can only set the program status and erase status bits in the status
register to
“1”; it cannot clear them to “0.”
The status register operates in this fashion for two reasons. The first is to give the
host CPU the flexibility to read the status bits at any time. Second, when
programming a string of bytes, a single status register query after programming the
string may be more efficient, since it will return the accumulated error status of the
entire string. See Section 3.2.3.1.
90
Intelligent
Identifier
Puts the device into the intelligent identifier read mode, so that reading the device
will output the manufacturer and device codes. (A
0
= 0 for manufacturer,
A
0
= 1 for device, all other address inputs are ignored). See Section 3.2.2.
