For the CC to start up correctly, the host must configure all the used buffers during the configuration state.
The host can reconfigure buffers partially during normal operation (see
Reconfiguration in the Normal State of
Figure
Each buffer is one of following:
Each double transmit message buffer consists of two parts — the host part buffer and the CC part buffer.
The host part buffer of a double transmit message buffer is a buffer with an even number configured as a
double transmit message buffer.
The CC part buffer of a double transmit message buffer is a buffer with the next (after the host part buffer)
number.
The accessibility of buffer fields depends on the buffer configuration. All information about buffer field
accessibility is summarized in
