OR3
Dout B1 Channel Timeslot Bits (7:0)
OR3(7:0) — Rx B1 Channel Timeslot
This register allows the B1 channel timeslot output from the Dout pin to be allocated 1 of 256 start
points, corresponding to each 2–bit boundary defined by the CLK. The timeslot can be either 8 or
10 CLKs wide. The default value for OR3 is 00H.

OR4(7:0) — Rx B2 Channel Timeslot
This register allows the B2 channel timeslot output from the Dout pin to be allocated 1 of 256 start
points, corresponding to each 2–bit boundary defined by the CLK. The timeslot can be either 8 or
10 CLKs wide. The default value for OR4 is 04H.

OR5(7:0) — Rx D Channel Timeslot
This register allows the D channel timeslot output from the Dout pin to be allocated 1 of 256 start points,
corresponding to each 2–bit boundary defined by the CLK. The default value for OR5 is 08H.
OR5(2:0) — GCI Timeslot, S(2:0)
In GCI indirect mode, control of the GCI timeslot is available through the S(2:0) bits. S(2:0)=0H is
the initialized state, timeslot 0. The timeslot selected must be compatible with the GCI DCL clock rate
being used; i.e., if the clock rate is 2048 kHz, only the first four timeslots are available. Bits 7:3 must
be programmed as 0.
