While programming the STPMIC1A with the USBSTICK – I2C to USB interface, I logged the I2C communication with an oscilloscope. This showed a command "Write, 66, DC 0C" that was send to the STPMIC just before the command to write the shadow registers to the NVM ("Write, 66, B9 01").
Exact logged I2C communication:
Write, 66, F8 EC 1A C2 08 FA 00 0E 33,
Write, 66, DC 0C,
Write, 66, B9 01,
However I was not able to found such command "DC 0C" on the STPMIC documentation.
Could you please explain what is this command used for? Is this command necessary when we are programming the STPMIC via the microprocessor in the application?
Thank you very much.
