Section 14 Serial Communication Interface (SCI)
Bit 5—Overrun Error (ORER): Indicates that an overrun error occurred during reception,
causing abnormal termination.
Bit 5: ORER
0
Description
Reception in progress, or reception has ended normally^*1
(Initial value)
[Clearing conditions]
• In a reset or in standby mode
• When 0 is written to ORER after reading ORER = 1
1
An overrun error occurred during reception^*2
[Setting condition]
When the next serial receive operation is completed while there are 16 receive
data bytes in SCFRDR
Notes: 1. The ORER flag is not affected and retains its previous state when the RE bit in SCSCR
is cleared to 0.
2. The receive data prior to the overrun error is retained in SCFRDR, and the data
received subsequently is lost. Serial reception cannot be continued while the ORER flag
is set to 1. Also, serial transmission cannot be continued in synchronous mode.
Bit 4—Framing Error (FER): Indicates a framing error in the data read from the receive FIFO
data register (SCFRDR).
Bit 4: FER
0
1
Description
There is no framing error in the receive data read from SCFRDR (Initial value)
[Clearing conditions]
• In a reset or in standby mode
• When there is no framing error in SCFRDR read data
There is a framing error in the receive data read from SCFRDR
[Setting condition]
When there is a framing error in SCFRDR read data
