Table 20: Control Byte C0

Bit 7
-
In the "6-Byte Mailbox" operating mode, only 1 common control byte is available
for both logical channels. For this reason, there is no more space in the status
byte to signal a wire break or short circuit. A short circuit or wire break is still
signaled by an under flow or overflow.
