Bit 7—Receive Error (ER): Indicates that a framing error or parity error occurred during
reception.
*1
Bit 7: ER
0
1
Notes: 1. The ER flag is not affected and retains its previous state when the RE bit in SCSCR2 is
cleared to 0. When a receive error occurs, the receive data is still transferred to
SCFRDR2, and reception continues.
The FER and PER bits in SCFSR2 can be used to determine whether there is a receive
error in the data read from SCFRDR2.
2. In 2-stop-bit mode, only the first stop bit is checked for a value of 1; the second stop bit
is not checked.

When the SCIF checks whether the stop bit at the end of the receive
data is 1 when reception ends, and the stop bit is 0*
•
