Section 12 Serial Communication Interface (SCI)
Bit 6—Receive Data Register Full (RDRF): Indicates that the received data is stored in RDR.
Bit 6
RDRF
0
1
Note: RDR and the RDRF flag are not affected and retain their previous values when an error is
Bit 5—Overrun Error (ORER): Indicates that an overrun error occurred during reception,
causing abnormal termination.

ORER
0

Notes: 1. The ORER flag is not affected and retains its previous state when the RE bit in SCR is

detected during reception or when the RE bit in SCR is cleared to 0.
If reception of the next data is completed while the RDRF flag is still set to 1, an overrun
error will occur and the receive data will be lost.
2. The receive data prior to the overrun error is retained in RDR, and the data received
cleared to 0.
subsequently is lost. Also, subsequent serial reception cannot be continued while the
ORER flag is set to 1. In clocked synchronous mode, serial transmission cannot be
continued, either.
Description
[Clearing conditions]
[Setting condition]
When serial reception ends normally and receive data is transferred from RSR to RDR
Description
[Clearing condition]
When 0 is written to ORER after reading ORER = 1
[Setting condition]
When the next serial reception is completed while RDRF = 1 *
When 0 is written to RDRF after reading RDRF = 1
When the DTC is activated by an RXI interrupt and reads data from RDR
