Bit 4—Error Signal Status (ERS): In Smart Card interface mode, bit 4 indicates the status of the
error signal sent back from the receiving end in transmission. Framing errors are not detected in
Smart Card interface mode.
Note: Clearing the TE bit in SCR to 0 does not affect the ERS flag, which retains its previous
Bits 3 to 0—Operate in the same way as for the normal SCI. For details, see section 14.2.7, Serial
Status Register (SSR).
However, the setting conditions for the TEND bit, are as shown below.
