Intel reserves other locations within the configuration address space for future use.
Read Status Register (70h)
The status register indicates the status of device operations, and the success/failure of that
operation.
The status register bits are output on DQ[7:0]. The upper byte, DQ[15:8], outputs 00h during a
Read Status Register command.
The contents of the status register are latched on the falling edge of F-OE# or F-CE#, whichever
occurs last. Latching on the falling edge prevents possible bus errors that might occur if status
register contents change while being read. F-CE# or F-OE# must be toggled with each subsequent
status read, or the status register does not indicate completion of a program or erase operation.
When the WSM is active, SR7 indicates the status of the WSM. The remaining bits in the status
register indicate whether the WSM was successful in performing the desired operation (see
