A more detailed error analysis can be done by the status information in
one of the following receive errors occurred:
– data could only partly stored due to internal buffer overflow of RB
– 3 consecutive frames had an error in the synchronization pattern
– a fast receive abort channel command was issued
– the data could not be transferred to the shared memory completely
– a receive abort channel command was active for at least
the receive descriptor.
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
one of the following errors occurred
– the data could not be transferred to the shared memory completely
– a fast receive abort channel command was issued
see Chapter 1.2
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
– the frame could not be transferred to the shared memory completely
– the frame was aborted by a fast receive abort channel command
the receive descriptor.

The MUNICH32 has discarded one or more whole frames or short
(loss of synchronism)
because of a hold bit set in a receive descriptor not providing enough
