10.0
Before a device can be programmed, it must be placed
in Serial Execution mode.
The procedure for entering Serial Execution mode con-
sists of verifying that the device is not code-protected.
If the device is code-protected, a Chip Erase must be
performed. See 9.0 “Erasing the Device” for details.
