Data Sheet
Short/Small Frame Drop Enable
This bit enables either the drop of short frames or the drop of small
frames. This bit is valid in HLDC and PPP modes only.
0
1
TMA Flag
This bit enabled flag extraction in TMA mode and is available if non of
the bits belonging to this channel is masked.
0
1
Bit Inversion
When bit inversion is enabled incoming channel data is inverted before
processed by the protocol machine. E.g. incoming octet 81
recognized as idle flag in HDLC mode.
0
1
Transparent Mode Packing
This bit enables the transparent mode packing and is valid in TMA mode
only. This feature is applicable if at least one bit in any time slot is
masked.
0
1
CRC Transfer
This bit enables the capability to store the CRC checksum of incoming
data packets in system memory together with the payload data.
0
1
Short Frame Drop. Frames smaller than four bytes payload data
(CRC32) or smaller than two bytes payload data (CRC16) are
dropped. This function is not available if bit CRCX is enabled.
Small Frame Drop. Frames (Payload and CRC) which are
smaller or equal to CONF3.MINFL are dropped.
No flag extraction
Enable flag extraction. The flag specified in RFLAG will be
extracted from the received data stream.
No Bit Inversion
Bit Inversion
Incoming masked bits are substituted with ‘1’. The non-used
(masked) data bits are substituted by ‘1’s.
If subchanneling is used in transparent mode (i.e. less than 8 bits
of a time slot are used), the non-used (masked) data bits are
discarded.
The CRC checksum from the incoming data packet will be
removed from the packet and not transferred to the shared
memory.
The CRC checksum together with the payload data is transferred
to the shared memory.
