PN5180 modulation index for ISO14443B设置

Hi,all

我最近在使用PN5180过 EMV Contactless L1时发现typeB 波形的调制深度偏小,因此我想通过修改默认的调制深度(Default modulation index for ISO14443B.)来加大调制深度,但是无论修改

#define PHHAL_HW_PN5180_MODINDEX_I14443B  0xCCU   这个的值调制深度都没有变化。我使用CLRC663时就是用这种方法修改的,但是在PN5180上为什么不行呢,是我改错地方了吗?我应该怎么调整typeB modulation index呢?

 

/** \name Modulation indices
*/
/*@{*/
#define PHHAL_HW_PN5180_MODINDEX_I14443B  0xCCU /**< Default modulation index for ISO14443B. */
#define PHHAL_HW_PN5180_MODINDEX_FELICA  0x17U /**< Default modulation index for Felica. */
#define PHHAL_HW_PN5180_MODINDEX_I15693  0x10U /**< Default modulation index for ISO15693. */
#define PHHAL_HW_PN5180_MODINDEX_EPCUID  0x10U /**< Default modulation index for EPC/UID. */
#define PHHAL_HW_PN5180_MODINDEX_I18000P3M3  0x10U /**< Default modulation index for ISO18000-3 Mode3. */
