## Detailed Description

## Function Documentation

## ◆ SCLIB_Activate()

int32_t SCLIB_Activate | ( | uint32_t | num,
|  | uint32_t | u32EMVCheck
| ) |  |

Activate a smartcard.

Parameters

  [in] | num | Smartcard interface number. From 0 ~ ( SC_INTERFACE_NUM - 1)
  [in] | u32EMVCheck | Enable EMV error check or not. Valid setting are TRUE and FALSE. By enable EMV error checking, this library will perform ATR checking according to EMV book 1 specification. Otherwise, the error checking follows ISO 7816-3

Returns
  Smartcard successfully activated or not

Return values

  SCLIB_SUCCESS | Smartcard activated successfully
  Others | Smartcard activation failed

Note
  It is required to set smartcard interface clock between 1 MHz and 5 MHz before calling this API, otherwise this API return with SCLIB_ERR_CLOCK error code.
  EMV book 1 is stricter than ISO-7816 on ATR checking. Enable EMV check iff the application supports EMV cards only.

## ◆ SCLIB_ActivateDelay()

int32_t SCLIB_ActivateDelay | ( | uint32_t | num,
|  | uint32_t | u32EMVCheck,
|  | uint32_t | u32Delay
| ) |  |

Activate a smartcard with large delay between set VCC high and start CLK output.

Parameters

  [in] | num | Smartcard interface number. From 0 ~ ( SC_INTERFACE_NUM - 1)
  [in] | u32EMVCheck | Enable EMV error check or not. Valid setting are TRUE and FALSE. By enable EMV error checking, this library will perform ATR checking according to EMV book 1 specification. Otherwise, the error checking follows ISO 7816-3
  [in] | u32Delay | Extra delay time between set VCC high and start CLK output, using ETU as time unit.

Returns
  Smartcard successfully activated or not

Return values

  SCLIB_SUCCESS | Smartcard activated successfully
  Others | Smartcard activation failed

Note
  It is required to set smartcard interface clock between 1 MHz and 5 MHz before calling this API, otherwise this API return with SCLIB_ERR_CLOCK error code.
  EMV book 1 is stricter than ISO-7816 on ATR checking. Enable EMV check iff the application supports EMV cards only.
  Only use this function instead of SCLIB_Activate if there's large capacitor on VCC pin and VCC raise slowly.
