Question 1: are there any benefits to using standalone PD controller like STSUB1600 over integrated solution STM32G0x1Question 2: are there code examples that are reasonably close to the DRP functionality ? In all the X-CUBE-USB-PD examples I've see...

The errata suggest to "insert a dummy phase with at least two dummy cycles" when using indirect data read mode.However, according to the documentation of the dummy cycle phase (AN4760 rev 3, section 3.1.4 and figure 8 ) states that in the dummy phase...

Thanks for the information. So I'll try to summarize what I learned - would appreciate corrections for any mistakes :The "sourcing device" functionality sample code is available for STM32F072 CPU and STUSB1602 PD controller (can't be used as direct r...

Well, if implemented as designed (without the errata bugs), it would have been extremely useful in interfacing to modern multi-lane ADC and DAC ICs.probably the only option as is would be to switch to different CPU or insert FPGA in the middle :unamu...

Looking for closest software example for implementing Dual Role Power UFP port. According to specification, such port should identify as power sink during initialization, and (in our application) after initialization perform a power role swap command.

STM32H74x Errata 2.5.3 QuadSPI - is the provided workaround feasible for read operation ?
