SFD for IEEE-1588 time stamping in DP83867

feng xu4

Hi,TI engineers。When I Refer to TI Application Report SNLA242 （How to Configure DP83867 SFDs），it is said that Set the internal SFD configuration by writing 0xDF22 to register 0x00E9. But I could not find the register 0x00E9 in the DP83867IRPAP datasheet。 Could you tell me why？Thanks!

Some of registers are not disclosed, and we could find that the register is 0x00FE after 0X00D3.

Hi，chen! apperatiated for your reply , if some registers are not disclosed, how could I set sfd configuration, and what do you mean that the register is 0x00FE after 0X00D3?

我的意思是在数据手册上，register map中0x00D3的寄存器之后就是0x00FE，显然还有一部分寄存器disclosed。

关于如何配置0x00E9寄存器，我需要再确认一下。
