DCI_CR
DPS_D ... Data Port Selection for D-Channel Timeslot access
0: The B-channel controller data is output on DD.
1: The B-channel controller data is output on DU.
EN_D ... Enable D-Channel Timeslot (2-bit) for B-Channel controller access
EN_BC2 ... Enable B2-Channel Timeslot (8-bit) for B-Channel controller access
EN_BC1 ... Enable B1-Channel Timeslot (8-bit) for B-Channel controller access
These bits individually enable/disable the B-channel access to the 2-bit and the two 8-bit
timeslots.
0: B-channel B/A does not access timeslot data B1, B2 or D, respectively.
1: B-channel B/A does access timeslot data B1, B2 or D, respectively.
Note: The terms B1/B2 should not imply that the 8-bit timeslots must be located in the
CS2-0 ... Channel Select for D-Channel Timeslot access
This register is used to select one of eight IOM channels. If enabled (EN_D=1), the
B-channel controller is connected to the 2-bit D-channel timeslot of that IOM channel.
Note: The reset value is determined by the channel select pins CH2-0 which are directly
4.4.6
Value after reset: A0
Read and write access to this register is only possible if IOM_CR.CI_CS = 0.
DPS_CI1 ... Data Port Selection CI1 Handler Data
0: The CI1 handler data is output on DD and input from DU
1: The CI1 handler data is output on DU and input from DD
