Receiver muting and wake-up feature

In multiprocessor configurations it is often desirable that only the intended message

recipient should actively receive the full message contents, thus reducing redundant SCI

service overhead for all non-addressed receivers.

The non-addressed devices may be placed in sleep mode by means of the muting function.

Setting the RWU bit by software puts the SCI in sleep mode:

All the reception status bits can not be set.

All the receive interrupts are inhibited.
