Maximum Frame Length Exceeded
The ’Maximum Frame Length Exceeded’ interrupt vector is generated,
when the length of a received data packet exceeded the frame length
defined in CONF1.MFL.
Receive Frame Overflow DMA
The ’Receive Frame Overflow DMA’ interrupt indicates that protocol
handler was unable to transfer data to the receive buffer. As soon as
receive buffer can store data again, this interrupt is generated.
CRC Error
The ’CRC Error’ interrupt vector is generated, when the internally
calculated CRC and the CRC of a received packet did not match.
Invalid Length
The ’Invalid Length’ interrupt vector is generated, when the bit length of
received frame was not divisible by 8.
Descriptor ID
This bit field is a copy of the descriptor ID of the transmit descriptor which
is currently in use. It can be used for tracking purposes.
(Transmit) Host Initiated Interrupt
The ’(Transmit) Host Initiated’ interrupt vector is generated, if bit THI is
set in a transmit descriptor and processing of this descriptor has finished.
After receiving this interrupt vector, system software can release the
descriptor, e.g. put the descriptor into a free pool.
Transmit Abort
The ’Transmit Abort’ interrupt vector is generated, either when the
’Transmit Abort/Branch’ command was given and therefore one frame
could not be transmitted completely or when NO and FE were set to 0 in
a transmit descriptor and previous frame was incompletely specified.
