AM64x TRM SPRUIM2H October 2023
Section 12.2.4.2.3 as quoted:
12.2.4.2.3 VBUS Sense
The VBUS voltage needs to be monitored for detection of the various valid signals (SESSEND, AVALID,BVALID, and SESSEND).
The voltage of the VBUS signal is scaled down using an external resistor divider (as shown in Figure 12-1796), to limit the voltage applied to the VBUS pin. A zener diode is used to clamp the maximum intermediate voltage to 6.8 volts. The tolerance of resistors used must be less than 1%. The leakage current of the zener diode must be less than 100 nA at 5 V.
THIS SECTION NEEDS CORRECTION/EXPANSION
Question: that last all caps comment is in the TRM. Will there be an update to correct VBUS sense? My AM6442 application is a USB 2 DEVICE
