Description

R/(W)*

Receive Error

Indicates that a framing error or parity error

occurred during reception.*

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*

• 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

E bit in SCSMR

Notes: 1. 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 data read from

SCFRDR.

2. When the stop length is 2 bits, only the

first stop bit is checked for a value of 1;

the second stop bit is not checked.
