5.14 CMD_SET_CONTROL_STACK
This command uploads the control stack to the STK. This is used for both PP and
HVSP.
Note: The Control stack must always be uploaded before performing any
programming commands in high voltage mode if the STK600 has been powered
down.
To check if the controller has a valid control stack: Read
PARAM_CONTROLLER_INIT.
