An EEP should only occur when the SW issue a "stop" command for the HW fee-machine before it finishes transmitting all of the read-out cycle data.

This bug can be happening because of a malfunction in the busy flag, tracked in issue #17. Because this malfunction, the busy flag can not be fully trusted to indicate when the fee-machine is ready to receive a "stop" command from the SW. In commit 71cd1ad, a HW V18 was crated with a improved busy flag and need to be tested.
