In the datasheet of PCF50633, there are some words such as "Reset values are determined by the IC variant".
But I can't find the further description for that.
So, I have 2 questions:
1. What is the reset value of some registers of PCF50633? Can you give some documents?
It seems that the documents of PCF50633 are not open. I can get some from openmoko.org, but that aren't enough.
2. What is the difference between the PART numbers PCF50633HN/04/N3 and PCF50633HN/05/N3?
I see that the PCF50633HN/04/N3 can't work in GTA02v1.
The last questions:
What are the AUTO, DOWN1 and DOWN2 converters used for ? What are the LDOs used for ?
There are so many consumers: the CPU core 1.8V, SDRAM 3.3 V, CPU IO 3.3V, LCM, and so on. And there are many ouputs from PCF50633 too.
So, who supply who?
