• Manufacturer Part Number: peb20550
• Description: Extended Pcm Interface Controller
• Manufacturer: Infineon Technologies Corporation

Example
In PCM mode 0 and CFI mode 0 the following non-transparent CFI to CFI loop via PCM
port 0, time slot 0 shall be programmed:
Upstream: CFI port 2, time slot 4, bits 7 … 0 to PCM port 0, time slot 0, bits 7 … 0
W:MADR
W:MAAR
W:MACR
Downstream: CFI port 1, time slot 7, bits 7 … 0 from PCM port 0, time slot 0, bits 7 … 0
W:MADR
W:MAAR
W:MACR
The following sequence sets transmit time slot 0 of PCM port 0 to high impedance:
W:MADR
W:MAAR
W:MACR
