The bit rate error is given by the following equation:

Initialization: Before transmitting or receiving data, the smart card interface must be initialized as
described below. Initialization is also necessary when switching from transmit mode to receive
mode, or vice versa.
1. Clear the TE and RE bits to 0 in the serial control register (SCR).
2. Clear error flags ERS, PER, and ORER to 0 in the serial status register (SSR).
3. Set the parity bit (O/E) and baud rate generator select bits (CKS1 and CKS0) in the serial
4. Set the SMIF, SDIR, and SINV bits in the smart card mode register (SCMR).
When the SMIF bit is set to 1, the TxD pin and RxD pin are both switched from port to SCI pin
5. Set a value corresponding to the desired bit rate in the bit rate register (BRR).
6. Set the CKE0 bit in SCR. Clear the TIE, RIE, TE, RE, MPIE, TEIE, and CKE1 bits to 0. If the
7. Wait at least one bit interval, then set the TIE, RIE, TE, and RE bits in SCR. Do not set the TE
mode register (SMR). Clear the C/A, CHR, and MP bits to 0, and set the STOP and PE bits to
