In the smart card interface mode, the function of bit 4 in SCSSR of the SCI is changed as shown
blow. Relating to this, the setting conditions for bit 2, the TEND bit, are also changed.

These bits have the same function as in the ordinary
SCI. See section 14, Serial Communication Interface
(SCI), for more information.
In the smart card interface mode, bit 4 indicates the
state of the error signal returned from the receiving
side during transmission. The smart card interface
cannot detect framing errors.
0: Receiving ended normally with no error signal.
1: An error signal indicating a parity error was
Note: The ERS flag maintains its state even when
transmitted from the receiving side.
[Clearing conditions]
1. The chip is reset or enters standby mode.
2. ERS is read as 1, then written to with 0.
[Setting condition]
The error signal sampled is low.
the TE bit in SCSCR is cleared to 0.
