20.1.4. Mode 3: 9-Bit UART, Variable Baud Rate
Mode 3 uses the Mode 2 transmission protocol with the Mode 1 baud rate generation. Mode 3 operation transmits
11 bits: a start bit, 8 data bits (LSB first), a programmable ninth data bit, and a stop bit. The baud rate is derived from
Timer 1 or Timer 2 overflows, as defined by Equation 20.1 and Equation 20.2. Multiprocessor communications and
hardware address recognition are supported, as described in
