Section 14 Smart Card Interface

Initialization
Before transmitting or receiving data, initialize the smart card interface by the procedure below.
Initialization is also necessary when switching from transmit mode to receive mode or from
receive mode to transmit mode.
1. Clear the TE and RE bits to 0 in the serial control register (SCR).
2. Clear the ERS, PER, and ORER error flags to 0 in the serial status register (SSR).
3. Set the parity mode bit (O/E) and baud rate generator clock source select bits (CKS1 and
4. Set the SMIF, SDIR, and SINV bits as required in the smart card mode register (SCMR).
5. Set a value corresponding to the desired bit rate in the bit rate register (BRR).
6. Set clock enable bit 0 (CKE0) as required in the serial control register (SCR). Write 0 in the
7. Wait for at least the interval required to transmit or receive one bit, then set the TIE, RIE, TE,

and MP bits to 0, and set the STOP and PE bits to 1.
When the SMIF bit is set to 1, the TxD
