to a max 2.76 Mbit/s. The interfaces support 3.3V only. The controllers can be used in
the low-speed, full-speed, and high-speed modes. The UART controllers are based on
the 16550 industry standard. The UART interfaces can be utilized to support various
sensors or a Bluetooth* device on the platform.
