Caution:
Receiver muting and wakeup 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:
A muted receiver may be awakened by one of the following two ways:
●
●
A receiver wakes up by Idle Line detection when the Receive line has recognized an Idle
Frame. Then the RWU bit is reset by hardware but the Idle bit is not set.
A receiver wakes up by Address Mark detection when it received a ‘1’ as the most significant
bit of a word, thus indicating that the message is an address. The reception of this particular
word wakes up the receiver, resets the RWU bit and sets the RDRF bit, which allows the
receiver to receive this word normally and to use it as an address word.
In Mute mode, do not write to the SCICR2 register. If the SCI is in Mute mode during the
read operation (RWU = 1) and an address mark wakeup event occurs (RWU is reset) before
the write operation, the RWU bit will be set again by this write operation. Consequently the
address byte is lost and the SCI is not woken up from Mute mode.
Parity control
Parity control (generation of parity bit in transmission and parity checking in reception) can
be enabled by setting the PCE bit in the SCICR1 register. Depending on the frame length
defined by the M bit, the possible SCI frame formats are as listed in
Table 59.
1. SB = Start bit, STB = Stop bit, and PB = Parity bit.
2. In case of wakeup by an address mark, the MSB bit of the data is taken into account and not the Parity bit.
All the reception status bits cannot be set.
All the receive interrupts are inhibited.
by Idle Line detection if the Wake bit is reset,
by Address Mark detection if the Wake bit is set.
