USART COMMUNICATIONS
Universal Synchronous Asynchronous Receive Transmit (USART) protocol is a stan-
dard 2-wire serial communication. In Asynchronous mode, there is a transmit line and
a receive line. In Synchronous mode, the transmit line becomes the clock line and the
receive line becomes the bidirectional data line. In Asynchronous mode, 8 bits are
framed by a Start and Stop bit. A ninth bit can be included to use as a parity bit.
To configure the protocol, set the clock polarity to rising edge or falling edge if using
Synchronous mode. Enable or disable 9-bit words and enable or disable the asynchro-
nous receiving ability of the PICkit™ Serial Analyzer. Select the baud rate according to
the BRG table.
