Section 14 Smart Card Interface
Bit 2—Smart Card Data Invert (SINV): Specifies inversion of the data logic level. This
function is used together with the SDIR bit for communication with an inverse convention card.
The SINV bit does not affect the logic level of the parity bit. For parity-related setting procedures,
see section 14.3.4, Register Settings.
Bit 1—Reserved: Read-only bit, always read as 1.
Bit 0—Smart Card Interface Mode Select (SMIF): Enables or disables the Smart Card interface
function.
14.2.2
Note:
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).
