The following logic input functions are used exclusively for the bus transfer scheme. Refer to Section 5.8.7: Transfer on

If the bus transfer feature is required, all logic input functions necessary for the operation of this scheme must be
assigned to contact inputs before any other functions. This is to ensure there are no conflicts.
