Hello,
Hello, I'm trying to read VENDOR_ID_LO register, All the registers i try reading from the USB group address (0x48) are read as 0x00 and not as thier Reset Value, for example VENDOR_ID_LO supposed to be 0x51. According to TPS65930/TPS65920 OMAP™ Power - Management and System Companion Devices Silicon Revision 1.2 Version F Technical Reference Manual - there are pre-requirement in order to access the regular Registers (section 14.4.3 Register Access and Arbitration Scheme) .I have trouble with some, for example IFC_CTRL[3] clocksuspendm bit is low – which means that I work in low-power mod, I tried effecting it by setting to zero the VUSB_DEDICATED2[3] vusb3v1_sleep bit, with no success. Can anyone give me a FULL sequence for enabling Register Access for the USB group address (0x48) . Thank you in advance, Merav.
