uint32_t SMARTCARD_InitTypeDef::BaudRate

This member configures the SmartCard communication baud rate. The baud rate is computed using the following formula:

• IntegerDivider = ((PCLKx) / (8 * (hirda->Init.BaudRate)))
• FractionalDivider = ((IntegerDivider - ((uint32_t) IntegerDivider)) * 8) + 0.5

uint32_t SMARTCARD_InitTypeDef::CLKLastBit

Specifies whether the clock pulse corresponding to the last transmitted data bit (MSB) has to be output on the SCLK pin in synchronous mode. This parameter can be a value of SMARTCARD Last Bit

uint32_t SMARTCARD_InitTypeDef::CLKPhase

Specifies the clock transition on which the bit capture is made. This parameter can be a value of SMARTCARD Clock Phase

uint32_t SMARTCARD_InitTypeDef::CLKPolarity

Specifies the steady state of the serial clock. This parameter can be a value of SMARTCARD Clock Polarity

uint32_t SMARTCARD_InitTypeDef::Parity

Specifies the parity mode. This parameter can be a value of SMARTCARD Parity

Note:

When parity is enabled, the computed parity is inserted at the MSB position of the transmitted data (9th bit when the word length is set to 9 data bits; 8th bit when the word length is set to 8 data bits).

uint32_t SMARTCARD_InitTypeDef::Prescaler

Specifies the SmartCard Prescaler value used for dividing the system clock to provide the smartcard clock. The value given in the register (5 significant bits) is multiplied by 2 to give the division factor of the source clock frequency. This parameter can be a value of SMARTCARD Prescaler
