TPS65910A31 EEPROM sequence上电顺序请教

Other Parts Discussed in Thread: AM3352, TPS65910, AM3358

大家好:我用AM3352+TPS65910A31做设计,现在有上电顺序的几个疑问:

(1)TPS65910A PDF 6.3.2 Switch-On/-OffSequences 中focus.ti.com/.../tps65910.html. 网址失效,有没有新的链接?或者其他

          EEPROM sequence上电顺序的文档?

(2)TPS65910A PDF Figure 5-4 上显示PWRON按下后VIO输出1.8V电压,PWRHOLD为高电平,使能有效;我参考《

TPS65910Ax User's Guide For AM335x Processors》Figure3显示要先使能(PWRHOLD为高电平),使TPS65910A先工作,然后才能输出VIO 1.8V电压。

两者有矛盾,还是我理解错了?能不能提供一些TPS65910A PWRON与PWRHOLD区别或上电顺序的说明文档?
