22.1.4. 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, 3, or 4 overflows, as defined by Equation 22.1 and Equation 22.3.
Multiprocessor communications and hardware address recognition are supported, as described in
22.2.
