About MessageHandlingUnitV2

MessageHandlingUnitV2 is a unidirectional message channel with two APB interfaces, one for the sender and one for the receiver. There is one message handling unit for each sender and receiver pair.

The receiver can be powered off. A Q-Channel is provided for power control on the receiver side.

The message payload can be written directly to status registers. Multiple channels can be combined into a single message.
