Initialize data parameter structure for the HAL layer. The

phhalHw_Rc663_DataParams_t

structure is related to the card reader CLRC663 and stores some software configuration

parameters which MCU controls the reader through. This function initiates PCD card

reader. The third passed parameter is address of existing BAL data parameter structure.

Initiate bus connection type separately (line 164 or 169), because

phhalHw_Rc663_Init()

function (see section 2.2.2) sets RS232 interface by default, although real hardware bus

selection has been done in line 142.

/* Set the parameter to use the I2C interface */

halReader.bBalConnectionType = PHHAL_HW_BAL_CONNECTION_I2C;

Pointer to the HAL layer data parameter structure will be needed by following initiations

of upper layer data parameter structures.

173

pHal = &halReader;

Initialize the 14443-3A PAL (Protocol Abstraction Layer) component (see section 2.3.2).

181

PH_CHECK_SUCCESS_FCT(status, phpalI14443p3a_Sw_Init(&I14443p3a,

182

sizeof(phpalI14443p3a_Sw_DataParams_t), pHal));

This initialization is redundant, since MIFARE Classic is incompliant with the

ISO/IEC14443-4.

185

PH_CHECK_SUCCESS_FCT(status, phpalI14443p4_Sw_Init(&I14443p4,

186

sizeof(phpalI14443p4_Sw_DataParams_t), pHal, &I14443p4));

Initialize the MIFARE PAL component, due to it is implemented by

phalMfc_Authenticate()

function and PAL ISO14443-3A.

189

PH_CHECK_SUCCESS_FCT(status, phpalMifare_Sw_Init(&palMifare,

190

sizeof(phpalMifare_Sw_DataParams_t), pHal, &I14443p4));
