The pull-up resistors may be placed on either half. If you wish to use the halves independently, it is also possible to use 4 resistors and have the pull-ups in both halves.

Note that the total resistance for the connected system should be within spec at 2.2k-10kOhm, with an 'ideal' at 4.7kOhm, regardless of the placement and number.
