Select STOP and immediately afterwards MRES (within 1 second). If
there is more than 1 second between pressing the two keys, the memory
reset is not performed.

– When the STOP LED flashes quickly for approximately 3 seconds and
is then lit continuously again, the memory on the C7 CPU has been
reset.
– If the STOP LED of the C7 lights up without first flashing, then repeat
Steps 4 and 5.
7. Following the memory reset, you must set the C7 CPU explicitly to STOP
or RUN/RUNP otherwise the C7 CPU is still set to MRES.
Note
A memory reset does not affect the content of the C7 CPU flash memory.
How to delete the content of the flash memory is described in Volume 2,
Section 3.8.
