Note: Receive data corresponds to downstream direction, and transmit data
CS2-0 ... Channel Select for Transceiver D-channel
This register is used to select one of eight IOM channels to which the transceiver
D-channel data is related to.
Note: The reset value is determined by the channel select pins CH2-0 which are directly
4.4.4.1
Value after reset: 00
TRC_CR
Write access to this register is possible if IOM_CR.CI_CS = 0 or IOM_CR.CI_CS = 1.
Read access to this register is possible only if IOM_CR.CI_CS = 1.
CS2-0 ... Channel Select for the Transceiver C/I0 Channel
This register is used to select one of eight IOM channels to which the transceiver C/I0
channel data is related to. The reset value is determined by the MODE2-bit and the
channel select pins CH2-0 which are mapped to CS2-0.
4.4.5
Value after reset:08
The registers BCH_TSDP_BC1/2 (see above) select the IOM-2 timeslots for B-channel
controller access. For the B-channel controller two 8-bit timeslots can be selected
(position and direction).
This register BCH_CR is used to select the position (CS2-0) and direction (DPS_D) of
the 2-bit timeslot for the B-channel controller, and each of the three selected timeslots
(2 x 8-bit and 2-bit) is individually enabled/disabled (EN_BC1, EN_BC2, EN_D).

mapped to CS2-0. It should be noted that writing TR_CR.CS2-0 will also write to
TRC_CR.CS2-0 and therefore modify the channel selection for the transceiver
C/I0 data.
