• Manufacturer Part Number: pef20550
• Description: Extended Line Card Interface Controller Elic
• Manufacturer: Infineon Technologies Corporation

If the D-channel access procedure is programmed, the IDEC MODE registers must
additionally be programmed accordingly i.e. for each channel MODE = 2C
of 0C
Example
In a first step, the QUAT-S in IOM port 0, ch. 0 … 3 is programmed via the IOM-2 monitor
handler to the LT-T mode:
W:OMDR
W:MFSAR
W:CMDR_E = 01
R:STAR_E
W:MFFIFO
W:MFFIFO
W:CMDR_E = 04
R:ISTA_E
W:MFSAR
W:CMDR_E = 01
R:STAR_E
W:MFFIFO
W:MFFIFO
W:CMDR_E = 04
R:ISTA_E
W:MFSAR
W:CMDR_E = 01
R:STAR_E
W:MFFIFO
W:MFFIFO
W:CMDR_E = 04
R:ISTA_E
W:MFSAR
W:CMDR_E = 01
R:STAR_E
W:MFFIFO
W:MFFIFO
W:CMDR_E = 04
