When the IC card is set for the direct convention, the O/E bit is cleared to 0; for the inverse
convention, it is set to 1.
Sets the bit rate. For the method of computing settings, refer to section 30.4.4, Clocks.
Each interrupt can be enabled and disabled using the TIE, RIE, TEIE, and WAIT_IE bits.
By setting either the TE or RE bit to 1, transmission or reception is selected.
The CKE1 and CKE0 bits are used to select the clock output state. For details, refer to section
30.4.4, Clocks.
When the IC card is set for the direct convention, both the SDIR and SINV bits are cleared to
0; for the inverse convention, both are set to 1. The SMIF bit is always set to 1.
Figure 30.3 below shows the register settings and waveform examples at the start character for
two types of IC cards (a direct-convention type and an inverse-convention type).
For the direct-convention type, the logical level 1 is assigned to the Z state, and the logical
level 0 to the A state, and transmission and reception are performed in LSB-first. The data of
the above start character is then H'3B. Even parity is used according to the smart card
specification, and so the parity bit is 1.
