Note: * Only 0 can be written, to clear these flags.
Bit 4 of SSR has a different function in Smart Card interface mode. Coupled with this, the setting
conditions for bit 2, TEND, are also different.
Bits 7 to 5—Operate in the same way as for the normal SCI. For details, see section 13.2.7, Serial
Status Register (SSR).
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
