SW3683-v05.19.00 PN7462AU_ex_phExCcid列程如何设置Type B卡的10%ASK调制(Amplitude modulation index is required to be between 8 % and 14 %.),在函数phhalHw_PN7462AU_ApplyProtocolSettings中没有相应的设置,整个工程文件都找不到对寄存器CLIF_ANA_TX_AMPLITUDE_REG的配置?难道是通过EEPROM里的默认值来设置的吗?
It is controlled by TX_CLK_MODE_RM filed in CLIF_ANA_TX_CLK_CONTROL_REG register (address 0104h).
Have a great day,

Hi Kan_Li,
This is only used to adjust the waveform(Tx envelope shape). It can't adjust the modulation index or the modulation depth.
Hi Xia Shuang,
The modulation index or the modulation depth is controlled by TX_RESIDUAL_CARRIER field in CLIF_ANA_TX_AMPLITUDE_REG register (address 0108h).
Have a great day,
Kan
