X

WRITE access to RAM possible.

1.

Fix-parameter mode / Debug mode:

This setting allows to overwrite the RAM contents, which is useful during debugging.

Once the system is fully developed, this parameter should be set to “1”.

2.

Dynamic mode:

This setting could also be useful for dynamic system application, if the system

parameters should be changed “on the fly” after power-up. It is recommended to

program the parameters and burn it into the ROM first. All deviating run-time

parameters have then to be downloaded on the fly after power-up every time.

1

Off

WRITE access to RAM denied.

Set to “1” in the final product to avoid accidentally overwriting of the contents of the RAM registers.
