12. Serial Communication Interface
For Smart Card Interface (SMIF Bit in SCMR Set to 1): Indicates the status of the error signal
sent back from the receiving side during transmission. Framing errors are not detected in smart
card interface mode.
Bit 4

1
Note:
Bit 3—Parity Error (PER): Indicates that reception of data with parity added ended abnormally
due to a parity error in asynchronous mode.

Notes: 1. Clearing the RE bit to 0 in SCR does not affect the PER flag, which retains its previous
Bit 2—Transmit End (TEND): The function of this bit differs for the normal serial
communication interface and for the smart card interface. Its function is switched with the SMIF
bit in SCMR.

the RDRF flag. Serial receiving cannot continue while the PER flag is set to 1. In
synchronous mode, serial transmitting is also disabled.
Description
Normal reception, no error signal*
[Clearing conditions]
•
•
An error signal has been sent from the receiving side indicating detection of a
parity error
[Setting condition]
The error signal is low when sampled
Description
Receiving is in progress or has ended normally*
[Clearing conditions]
•
•
A receive parity error occurred*
[Setting condition]
The number of 1s in receive data, including the parity bit, does not match the
even or odd parity setting of O/E in SMR
The chip is reset or enters standby mode
Read ERS when ERS = 1, then write 0 in ERS
