an interrupt is generated to alert the host processor to the fact that a message was received.
When all three frame buffers are full the receive module can no longer receive CEC messages and will not acknowledge any new messages
(other than polling messages). In the case that only one frame buffer is enabled (the default condition) then only one message can be
received. In this case the received message is always available in buffer 0.
The host can read the receive buffers (refer to
length of each received message is available in the corresponding frame length register.
