你好,应用端调用什么函数可以读写cx3芯片的寄存器,我想读USB 3.0 PHY Transmitter Config Register 0xE003303C,然后试写此寄存器,验证usb数据是否有改善。或者哪里可以找到例子?

USB_FX3_Technical_Reference_Manual.pdf这个文档里485页里有关于

USB 3.0 PHY Transmitter Config Register的一些说明:

27:21 PCS_TX_SWING_LOW[6:0]

TX Amplitude (Low Swing Mode) in 10 mv units

20:14 PCS_TX_SWING_FULL[6:0]

TX Amplitude (Full Swing Mode) in 10 mv units

12:7 PCS_TX_DEEMPH_6DB[5:0]

TX de-emphasis at 6dB

5:0 PCS_TX_DEEMPH_3P5DB[5:0]

TX de-emphasis at 3.5dB

请问是否可以调整这个寄存器的配置,增加数据的稳定性?谢谢!

(*(volatile *)(0xE003303C))=0x000000ff

是这样类似操作吗?
