14.1 Features
• Full duplex operation with buffered receiver and transmitter.
• Internal baud rate generator with 12 programmable baud rates (300 - 115200).
• 7 or 8 bits word length.
• Even, odd, or no-parity bit generation and detection
• 1 stop bit
• Error receive detection: Start, Parity, Frame and Overrun
• Receiver echo mode
• 2 interrupts (receive full and transmit empty)
• Enable receive and/or transmit
• Invert pad Rx and/or Tx
14.2 Overview
The UART pins are PB[7], which is used as Rx - receive and PB[6] as Tx - transmit.
