OR3: D in B1 Timeslot Register
Programmed the same way as OR0. This register controls when the B1 timeslot is input from the
D in pin. After a hardware or software reset, all bits default to 0 to maintain MC145472/MC14LC5472
compatibility.
OR4: D in B2 Timeslot Register
Programmed the same way as OR0. This register controls when the B2 timeslot is input from the
D in pin. After a hardware or software reset, all bits default to 0 to maintain MC145472/MC14LC5472
compatibility.
OR5: D in D and GCI Timeslot Register
Programmed similar to OR2. This register controls when the D timeslot is input from the D in pin.
After a hardware or software reset, all bits default to 0 to maintain MC145472/MC14LC5472 com-
patibility.
GCI Slot (2:0)
In IDL2 mode, if OR6 b(3) is set to indicate GCI 2B+D operation, b(2:0) is used to program the GCI
timeslot. These bits are treated like the S2, S1, and S0 pins in Full GCI mode. See Table 3–7 for
timeslot assignment.
OR6: Timeslot and GCI Control Register
This register is used to enable the timeslot assigner and select GCI 2B+D data format when in IDL2
mode. After a hardware or software reset, all bits default to 0 to maintain MC145472/MC14LC5472
compatibility.

Setting b7, b6, or b5 will put the MC145572 in Timeslot Assigner mode. In Timeslot Assign-
er mode, the IDL2 8/10 mode bit in BR7(b0) is ignored and data is placed according to
values programmed in OR0 – OR5.
