UCD9090 GPO question

Other Parts Discussed in Thread: UCD9090

Hi,

I have a question about UCD9090 GPO configuration, below is my seeting.

Suppose :

a. GPI 1 : Low

b. GPI 2 : High

c. RAIL1[POWER_GOOD] : High

d. GPO2 : (GPI2 * RAIL1[POWER_GOOD]) + (GPO1)

When system start, what is the GPO 2 state (high or low) ??

GPO 4 is low, and GPO1 is low, too.

How about GPO2 ? In logical, it should be high (because GPI2 & RAIL1[POWER_GOOD] are high).

But, actually, it is Low.

I don't understand it, does it make sense ??
