Serial Interfaces
RS-232C
All CAN microcontrollers have one on-chip UART peripheral. Only the asynchronous
mode is supported by the AT89STK-06 board.
The AT89STK-06 board 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.
