SERIAL I/O (HIGH-SPEED UART)
11.3.10 HIGH-SPEED UART AUTOBAUD BOUNDARY REGISTER
This autobaud boundary register limit range of each baud rate value that is auto-detected. ABB0 is the lowest
boundary value (high baud rate) and ABB3 is the highest value (low baud rate) of autobaud boundary register
(actually the highest boundary value is ABT3). Refer figure 11-13 for detail range.
