MUNICH32 writes the number of data bytes it has stored in the current data
section into BNO.
The MUNICH32 writes the status information into the status byte whenever it
sets the C-bit. If the status information is not 00 or 40 an interrupt with ERR
bit set is generated. The status is then a means to locate or analyze the
receive error.
The following table gives a general overview over the different status bits in
relation to the channel modes.

C indicates that the second long word of the receive descriptor was written
by the MUNICH32. Afterwards the MUNICH32 writes the next receive
descriptor address into CCS. Then it branches to this descriptor
immediately.
