Hi Werner:
I set the MBCC7=3 (suspend) and MBCC8=0. I found the USB doesn't supply
any current for GTA02.
But I plug the USB power into GTA02, the PMU will change it's register
status. The MBCC will change back "1".
Can someone give me a SW which the MBCC always is "3"?
Therefore, I can make the DC-DC output 5V and found what happen?
Best Wish

o- either set max allowable USB current of PCF50633 to 0mA when in
hostmode,
That should work if we choose "suspend" in MBCC7.usbdevstat and set
MBCC8.usbenasus = 0
See also Figure 38 and Table 103.
Need verification, though. The PMU is complex enough for surprises ;-)
