4.5.4.4 Baud Rate Generation
The baud rate for the receiver and transmitter (Rx
and Tx) are set independently and calculated as
follows:
f
CPU
with:
PR = 1, 3, 4 or 13 (see SCP0 & SCP1 bits)
TR = 1, 2, 4, 8, 16, 32, 64,128
(see SCT0, SCT1 & SCT2 bits)
RR = 1, 2, 4, 8, 16, 32, 64,128
(see SCR0,SCR1 & SCR2 bits)
All these bits are in the BRR register.
Example:
If f
CPU
is 8 MHz and if PR=13 and
TR=RR=1, the transmit and receive baud rates are
19200 baud.
Note:
the baud rate registers MUST NOT be
changed while the transmitter or the receiver is en-
abled.
4.5.4.5 Receiver Muting and Wake-up Feature
In multiprocessor configurations it is often desira-
ble 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 interrupt are inhibited.
A muted receiver may be awakened by one of the
following two ways:
– by Idle Line detection if the WAKE bit is reset,
– by Address Markdetection iftheWAKE bitis set.
Receiver wakes-up by Idle Line detection when
the Receive line has recognised an Idle Frame.
Then the RWU bit is reset by hardware but the
IDLE bit is not set.
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 ad-
dress. The reception of this particular word wakes
up the receiver, sets 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.
