• Manufacturer Part Number: HD6412350
• Description: (HD6412350 / HD6432351) 16-BIT MICROCONTROLLER
• Manufacturer: Hitachi

Bit 5—Overrun Error (ORER): Indicates that an overrun error occurred during reception,
causing abnormal termination.

Notes: 1. The ORER flag is not affected and retains its previous state when the RE bit in SCR is
Bit 4—Framing Error (FER): Indicates that a framing error occurred during reception in
asynchronous mode, causing abnormal termination.

ORER flag is set to 1. In clocked synchronous mode, serial transmission cannot be
continued, either.

is not checked. If a framing error occurs, the receive data is transferred to RDR but the
RDRF flag is not set. Also, subsequent serial reception cannot be continued while the
FER flag is set to 1. In clocked synchronous mode, serial transmission cannot be
continued, either.
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
Description
[Clearing condition]
When 0 is written to FER after reading FER = 1
[Setting condition]
When the SCI checks whether the stop bit at the end of the receive data when
reception ends, and the stop bit is 0 *
