• Description: Multichannel Network Interface Controller For Hdlc With 32 Channels
• Manufacturer: Infineon Technologies Corporation

Fixed Size Frame Oriented Protocol (V.110/X.30)
Reaction to a channel specification containing TH = 1

2. The current frame processed, when TH = 1 is handed over to CD is aborted,
3. The data section DATA 1 is split in the example; DATA 1
4. The TH (as all channel commands) is not synchronized with TB. TH acts on
5. If TH is handed over to CD before a frame has started after an abort or after
only 10 – y, (y = 1, …, 10) octets of it are sent. The device then starts to send

aborted frame, all bits that were read into the MUNICH32 with the same access
are discarded (they would have been sent in the next frame(s) if TH = 1 was
not issued) and the device starts the next frame with the bits DATA 1
