You cannot program
“1”s to the flash. Writing FFH following the Program Setup will initiate the internal program algorithm
of the WSM. Although the algorithm will execute, array data is not changed. The WSM returns to read status mode without
reporting any error. Assuming V
PP
> V
PPLK
writing a second FFH while in read status mode will return the flash to read
array mode.
