Bit 2—Smart Card Data Inverter (SINV): Inverts data logic levels. This function is used in
combination with bit 3 to communicate with inverse-convention cards. SINV does not affect the
logic level of the parity bit. For parity settings, 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 the smart card interface function.
14.2.2
The function of SSR bit 4 is modified in the smart card interface. This change also causes a
modification to the setting conditions for bit 2 (TEND).
