LTC4013 Table 1 Confusion

Table 1 of the datasheet shows how to set the MODE pins for different battery chemistries and charge algorithms.  However, I am a bit confused by what the "M" designator means.  Does that mean to leave the I/O floating?

For reference, I am trying to use the IC as a Li-ion charger with "Wide" recharge hysteresis.  The example circuit for an LiFePO4 charger shown in Figure 20 shows the Mode pins floating, so I think "M" means floating; however, I would like to verify this 100%.


Thanks.



Added picture of circuit.
