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

After the clocks have been enabled this is indicated by the PU code in the C/I channel
and, consequently, by a CIC interrupt. The DU line may be released by resetting the
Software Power Up bit IOM_CR =’0’ and the C/I code written to CIX0 before (e.g. TIM or
AR8) is output on DU.
The ISAC-SX supplies IOM-2 timing signals as long as there is no DIU command in the
C/I (C/I0) channel. If timing signals are no longer required and activation is not yet
requested, this is indicated by programming DIU in the CIX0 register.
