11.3.2 USB Control Logic
The USB control logic handle the following functions:
11.3.3 USB Endpoint Configuration
A single configuration and 2 interfaces are supported by the module. Endpoint 0 is always used as control
endpoint. The interface number for endpoint 1 to 4 are programmable through USB interface control
register (UINTFCR). The endpoint type and direction of all endpoint 1 to 4 is software programmable to
either BULK or INTERRUPT and either IN or OUT respectively. The endpoint configuration is summarized
