RS-232C
The AT90CAN128 is a micro-controller with two on-chip USART peripherals, USART0.
and USART1. Only the asynchronous mode is supported by the DVK90CAN1.
The DVK90CAN1 is supplied with a RS-232 driver/receiver. Only one female DB9
connector assumes the RS-232 connections. A full range of configuration can be set
with two Rx lines and two Tx lines.
