USBFXStack Middleware Library v1.2.0

See the README.md and the USBFXStack API Reference Manual for a complete description of the USBFXStack.

Feature updates

Updated the USB driver stack to support all USB specification compliance requirements including correct handling of USB link low power states
Updated USB driver stack to support USB-C orientation detection on an external USB Power Delivery (PD) controller
New LVDS/LVCMOS init function supporting all interface frequencies within the supported range
Added capability to route debug log data through the USB Communication Device Class (CDC) interface added to the main USB device configuration
Updated Debug Design For Test (DDFT) select function to support observation of additional LVDS/LVCMOS related signals

Fixed occasional USB enumeration failures in different interoperability scenarios

The USB stack is not fully compliant with USB specification requirements for 20 Gbps (Gen2x2) devices and rare failures may be seen in link layer test cases. Such failures will be resolved in a subsequent release of the stack. Note that all compliance requirements for USB 2.x, 10 Gbps (Gen2x1), and 5 Gbps (Gen1x1) devices are already satisfied by this version of the stack

This version of the USBFXStack Middleware Library is validated for the compatibility with the following software and tools:

ModusToolbox™ software environment	3.4.0
CAT1A Peripheral Driver Library (PDL)	3.16.0
