Dear All,
The problem is that I can write to all writable registers. Then read the values back no problem.
But when I want to power on a "block" by writing some value to reg 0x01 at page 0x00. Nothing happens. When I read back all the registers, everything is reseted to 0x00. I.e. all the once that where set and readback correctly in the first place and also the 0x01 register. So none of the blocks is powered on.
What could cause that I cannot power on any block at reg 0x01?
