3.3.3.8
This flag indicates the reception of a valid communication element. A valid communication element is
either a syntactically and semantically correct frame or symbol.
0 – No valid communication element received in current slot.
1 – Valid frame received in current slot.
3.3.3.9
This flag indicates the channel the slot status refers to.
0 – Slot status of channel A.
1 – Slot status of channel B.
3.3.4
If the payload preamble bit PP is set, the message ID field holds the message ID of a dynamic frame located
in the message buffer. The FIFO filter may use the received message ID for message ID filtering.
3.3.5
If the payload preamble bit PP is set, the network management vector fields hold the network management
vector of a static frame located in the message buffer.
3.3.6
Receive message buffers:
The data fields store received frame payload data, if all the receive filtering criteria are met.
Transmit message buffers:
The host writes these data fields with payload data to be transmitted.
Receive FIFO:
The data fields in the FIFO buffer stores a received frame’s payload data values if the channel, message
ID, and cycle counter are accepted by the configured receive FIFO acceptance filter value and mask, and
not rejected by the configured receive FIFO rejection filter value and mask, and if there is no matching
dedicated receive message buffer in the mailbox.
