Initialize USART for reception from EDBG Virtual COM Port.

This function initializes the specified SERCOM USART driver instance for use with the Embedded Debugger (EDBG) Virtual COM Port. Both transmitter and receiver are enabled, but only the receive interrupt is enabled.

A custom handler function for the receive interrupt must must be supplied. See the SERCOM USART callback driver's handler for an implementation template: _usart_interrupt_handler().

Parameters

usart	Address of USART instance to use.
cdc_rx_handler	Address of receive interrupt handler.
