OR0
OR0(7:0) — Tx B1 Channel Timeslot
This register allows the B1 channel timeslot input to the D in 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 OR0 is 00H.
OR1
OR1(7:0) — Tx B2 Channel Timeslot
This register allows the B2 channel timeslot input to the D in 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 OR1 is 04H.
OR2
OR2(7:0) — Tx D Channel Timeslot
This register allows the D channel timeslot input to the D in pin to be allocated 1 of 256 start points,
corresponding to each 2–bit boundary defined by the CLK. The default value for OR2 is 08H.
