I am working on a new design using TWL6030 and I would like some precisions regarding the PWRON pin.
Pin L15: PWRON: External on-button switch-on even (primary input to launch system wakeup)
It is not clear to me whether a PWRON edge transition is mandatory for the TWL6030 to boot up. My design doesn't have a power button and simply turns on/off when power is applied or removed (it runs on a power supply, not on a battery). There is no wake-up event other than the power being applied.
The previous generation had a TPS65950 and we had tied PWRON high with a pull-up resistor and it worked good. Can I do the same with TWL6030?
If power on is not used leave it not connected. There is an internal pull up which is ok.
In the documentation of TWL6030, I cannot find any information about "OMAP Power Management" goals (I am using a Pandaboard Rev A4). I am wondering if there are the same registers and addresses as are in TPS65950 (that have been used in beagle-board)? Do TWL6030 and TPS65950 have the same structure?
TWL6030 uses a different register programing model versus TPS65950. This document is delivered under non disclosre agrement. Please contact your TI representative.
Thank for the quick reaction and answer. I did not understand well. With whom exactly do I have to contact for TWL6030 document?
