Transmit Message Buffer Slot Status Description
This section describes the slot status structure for transmit message buffers. Only the TCA and TCB status
bits are directly related to the transmission process. All other status bits in this structure are related to a
receive process that may have occurred. The content of the slot status structure for transmit message
buffers depends on the channel assignment as given by

Channel first valid received — This status bit applies only to receive message buffers assigned to the static
segment and to both channels. It indicates the channel that has received the first valid frame in the slot. This flag
is set to ‘0’ if no valid frame was received at all in the subscribed slot.
