15. Serial Communication Interface (SCI)
Bit 6—Receive Data Register Full (RDRF): Indicates that the received data has been stored in
SCRDR1.
Bit 6: RDRF
0
1
Note: SCRDR1 and the RDRF flag are not affected and retain their previous values when an error
Bit 5—Overrun Error (ORER): Indicates that an overrun error occurred during reception,
causing abnormal termination.
Bit 5: ORER
0
1
Notes: 1. The ORER flag is not affected and retains its previous state when the RE bit in

is detected during reception or when the RE bit in SCSCR1 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 SCRDR1, and the data
SCSCR1 is cleared to 0.
received subsequently is lost. Serial reception cannot be continued while the ORER flag
is set to 1. In synchronous mode, serial transmission cannot be continued either.
Description
There is no valid receive data in SCRDR1

•
There is valid receive data in SCRDR1
[Setting condition]
When serial reception ends normally and receive data is transferred from
SCRSR1 to SCRDR1
Description
Reception in progress, or reception has ended normally*

An overrun error occurred during reception*
[Setting condition]
When the next serial reception is completed while RDRF = 1
Power-on reset, manual reset, standby mode, or module standby
When 0 is written to RDRF after reading RDRF = 1
When data in SCRDR1 is read by the DMAC
