Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Receive Error
Indicates that a framing error or parity error
occurred during reception. The ER flag is not
affected and retains its previous state when the
RE bit in SCSCR is cleared to 0. When a receive
error occurs, the receive data is still transferred to
SCFRDR, and reception continues.
The FER and PER bits in SCFSR can be used to
determine whether there is a receive error in the
readout data from SCFRDR.
0: No framing error or parity error occurred during
reception
[Clearing conditions]
• Power-on reset or manual reset
• When 0 is written to ER after reading ER = 1
1: A framing error or parity error occurred during
reception
[Setting conditions]
• 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*²
• When, in reception, the number of 1-bits in the
receive data plus the parity bit does not match
the parity setting (even or odd) specified by
the O/E bit in SCSMR
