TMS320C6678: RESETFULL引脚能否在上电时处于无效状态

Part Number: TMS320C6678
Other Parts Discussed in Thread: TPS3808

datasheet 第123页 图7-3展示了一种上电时序,CORE before io Power sequencing, 并且明确说明了 ResetFull要在 POR变高多保持为低一段时间。我对此话有异议。我觉得POR应该是和RESETFULL独立的,是一种或的关系。我想装一个按钮,可以手动Resetfull。不可能上电时一直按着按钮RESETFULL使它有效的。

请确认ResetFull要在 POR变高多保持为低一段时间
