HAL SMARTCARD Generic Driver
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
uint32_t SMARTCARD_InitTypeDef::GuardTime
Specifies the SmartCard Guard Time value in terms of number of baud clocks
uint32_t SMARTCARD_InitTypeDef::NACKState
Specifies the SmartCard NACK Transmission state. This parameter can be a value of
SMARTCARD_NACK_State

42.2 SMARTCARD Firmware driver API description
42.2.1 How to use this driver
The SMARTCARD HAL driver can be used as follows:
1. Declare a SMARTCARD_HandleTypeDef handle structure.
2. Initialize the SMARTCARD low level resources by implementing the
HAL_SMARTCARD_MspInit() API:
a. Enable the USARTx interface clock.
b. SMARTCARD pins configuration:
