Reference Information: Hardware: UCD9020EVM-783 with USB to GPIO adapter; Software: Fusion Digital Power Designer Version 7.5.1
Rail Configuration: Rail #1 (renamed to 1.2V_POL_1)
On/Off Config: Operation Only (0x1A)
On/Off Timing: 0/0
Sequence Timeout: On Sequence: 0, Wait Indefinitely; Off Sequence: 0, Wait Indefinitely
Sequence On Dependencies: Rails On Dependencies: None; Rails Off Dependencies: None; GPIs On/OFF Dependencies: GPI #4 (C8 LGPO04 (GPIO)) - I've configured this GIPO as a GPI; checked On and checked OFF for this GPI; GPOs On/Off Dependencies: None
On the System Monitor screen, I can click Operation Cmd to ON, and the Rail #1 Enable does not go on until I also connect a pullup to GPI #4 input. When I connect the pullup, the Enable goes high as expected (i.e. I'm attempting to gate Rail #1 with GPI #4). But when I disconnect (de-assert) the pullup from the GPI #4 input, the Enable stays on for Rail #1. What I would like to have happen is the Rail #1 Enable follows the state of the GPI #4 input, like a simple gating function. I have not been able to get this to happen. Is it possible?
Thanks,
Mike
