ASYNCHRONOUS SERIAL COMMUNICATIONS INTERFACE (Cont’d)
10.6.4.3 Receiver
The SCI can receive data words of either 8 or 9
bits. When the M bit is set, word length is 9 bits
and the MSB is stored in the R8 bit in the SCICR1
register.
Character Reception
During a SCI reception, data shifts in least signifi-
cant bit first through the RDI pin. In this mode, the
SCIDR register consists or a buffer (RDR) be-
tween the internal bus and the received shift regis-
ter (see
Procedure
– Select the M bit to define the word length.
– Select the desired baud rate using the SCIBRR
– Set the RE bit, this enables the receiver which
When a character is received:
– The RDRF bit is set. It indicates that the content
– An interrupt is generated if the RIE bit is set and
– The error flags can be set if a frame error, noise
Clearing the RDRF bit is performed by the following
software sequence done by:
1. An access to the SCISR register
2. A read to the SCIDR register.
The RDRF bit must be cleared before the end of the
reception of the next character to avoid an overrun
error.
Break Character
When a break character is received, the SCI han-
dles it as a framing error.
Idle Character
When a idle frame is detected, there is the same
procedure as a data received character plus an
iterrupt if the ILIE bit is set and the IMI0 bit is set in
the SIMRH register.

ception.

ASYNCHRONOUS SERIAL COMMUNICATIONS INTERFACE (SCI-A)
Overrun Error
An overrun error occurs when a character is re-
ceived when RDRF has not been reset. Data can
not be transferred from the shift register to the
TDR register as long as the RDRF bit is not
cleared.
When a overrun error occurs:
– The OR bit is set.
– The RDR content will not be lost.
– The shift register will be overwritten.
– An interrupt is generated if the RIE bit is set and
The OR bit is reset by an access to the SCISR reg-
ister followed by a SCIDR register read operation.
Noise Error
Oversampling techniques are used for data recov-
ery by discriminating between valid incoming data
and noise.
When noise is detected in a frame:
– The NF is set at the rising edge of the RDRF bit.
– Data is transferred from the Shift register to the
– No interrupt is generated. However this bit rises
The NF bit is reset by a SCISR register read oper-
ation followed by a SCIDR register read operation.
Framing Error
A framing error is detected when:
– The stop bit is not recognized on reception at the
– A break is received.
When the framing error is detected:
– the FE bit is set by hardware
– Data is transferred from the Shift register to the
– No interrupt is generated. However this bit rises

ation followed by a SCIDR register read operation.
