8 Detailed Description
8.1 Overview
The TUSB2E221 is a dual eUSB2 to USB 2.0 repeater that resides between SoC with one or two eUSB2 port
and an external connector that supports USB 2.0. Each repeater is independently configurable as either a host
or device repeater (DRD repeater).
The USB 2.0 ports A and B can be swapped by an internal crossbar switch by configuring CROSS pin at reset.
The CROSS pin is ignored after power up reset.
