• Manufacturer Part Number: PEB3086
• Description: ISDN Subscriber Access Controller
• Manufacturer: Infineon Technologies

EN_CI1 ... Enable CI1 Handler Data
0: CI1 handler data access is disabled
1: CI1 handler data access is enabled
Note: The timeslot for the C/I1 handler cannot be programmed but is fixed to IOM
D_EN_D ... Enable D-timeslot for D-channel controller
D_EN_B2 ... Enable B2-timeslot for D-channel controller
D_EN_B1 ... Enable B1-timeslot for D-channel controller
These bits are used to select the timeslot length for the D-channel HDLC controller
access as it is capable to access not only the D-channel timeslot. The host can
individually enable two 8-bit timeslots B1- and B2-channel (D_EN_B1, D_EN_B2) and
one 2-bit timeslot D-channel (D_EN_D) on IOM-2. The position is selected via CS2-0.
0: D-channel controller does not access timeslot data B1, B2 or D, respectively
1: D-channel controller does access timeslot data B1, B2 or D, respectively
CS2-0 ... Channel Select for D-channel controller
This register is used to select one of eight IOM channels. If enabled, the D-channel data
is connected to the corresponding timeslots of that IOM channel.
Note: The reset value is determined by the channel select pins CH2-0 which are directly
4.4.6.1
Value after reset: 00
DCIC_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 C/I0 Handler
This register is used to select one of eight IOM channels. If enabled, the data of the
C/I0 handler is connected to the corresponding C/I0 timeslot of that IOM channel. The
reset value is determined by the channel select pins CH2-0 which are mapped to CS2-0.

channel 1.
mapped to CS2-0. It should be noted that writing DCI_CR.CS2-0 will also write to
DCIC_CR.CS2-0 and therefore modify the channel selection for the data of the
C/I0 handler.
