–
a receive abort channel command was active for at least
3 consecutive frames
A more detailed error analysis can be performed by the status
information in the Rx descriptor.
2.2 V.110/X.30 mode
Transmit Direction
one of the following transmit errors occurred
–
the last descriptor had a HOLD = 1 or FE = 1
–
the last descriptor had FE = 0 and NO = 0
3.1 TMA mode
Receive Direction
one of the following errors occurred
–
the data could not be transferred to the shared memory completely
because of a HOLD bit set in a Rx descriptor not providing enough
bytes for the data
–
a fast receive abort channel command was issued
3.2 TMA mode
Transmit Direction
see
Chapter
1.2
4.1 TMB/TMR mode
Receive Direction
always in conjunction with FI = 1
one of the following receive errors occurred
–
the bit length of the frame was not divisible by 8
–
the frame could only be partly stored due to
internal buffer overflow of RB
–
the frame could not be transferred to the shared memory completely
because of a HOLD bit set in a Rx descriptor not providing enough
bytes for the frame
–
the frame was aborted by a fast receive abort channel command
A more detailed error analysis can be performed by the status
information in the Rx descriptor.
4.2 TMB/TMR mode
Transmit Direction
see
Chapter
1.2
1.1 HDLC, TMB, TMR
Receive Direction
The MUNICH32X has discarded one or more whole frames or short
frames or change of interframe time-fill informations due to inaccessibility
of the internal buffer RB.
1.2 HDLC, TMB, TMR
Transmit Direction
The MUNICH32X is unable to access the shared memory in time or has
detected a fatal bus cycle error during a read access on the transmit data
section. The current erroneous frame is aborted with a
‘
0
’
and 14
‘
1
’
for
HDLC, with
‘
00
’
for TMB and
‘
0000
’
for TMR; afterwards interframe time-
fill is sent until the MUNICH32X can access again the shared memory.
