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 SCRDR 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.
