Bit Bit Name
Initial
Value R/W Description
7 ER 0 R/(W)* Receive Error
Indicates the occurrence of a framing error, or of a
parity error when receiving data that includes parity.*
1
0: Receiving is in progress or has ended normally
[Clearing conditions]
ER is cleared to 0 a power-on reset
ER is cleared to 0 when the chip is when 0 is
written after 1 is read from ER
1: A framing error or parity error has occurred.
[Setting conditions]
ER is set to 1 when the stop bit is 0 after checking
whether or not the last stop bit of the received
data is 1 at the end of one data receive
operation*
2
ER is set to 1 when the total number of 1s in the
receive data plus parity bit does not match the
even/odd parity specified by the O/E bit in SCSMR
Notes: 1. Clearing the RE bit to 0 in SCSCR does
not affect the ER bit, which retains its
previous value. Even if a receive error
occurs, the receive data is transferred to
SCFRDR and the receive operation is
continued. Whether or not the data read
from SCFRDR includes a receive error
can be detected by the FER and PER bits
in SCFSR.
2. In two stop bits mode, only the first stop
bit is checked; the second stop bit is not
checked.
