SYSRESET signal of AM3874

Michi Yama
Guru 10030 points

Hi,

I have one question.

In TRM (SPRUGZ7B),   it is written "SYSRESET" signal. But I can't find any description of "SYSRESET" in TRM or datasheet.

I think this signal is important. Because this signal is used for PLL setting.

Does anyone know the specification of SYSRESET? 

Best regards,

Michi

    Hi Michi,

    From my understanding, the "SYSRESET" is system reset at device level (not local to some module reset). Please check section 2.7.11 Reset Characteristics, table 2-36. Reset Sources. All system level reset sources (except TRSTz) are affecting the device PLLs. So I assume SYSRESET is common name to all these system level reset signals.

    Regards,
