UART Baud Rate Divisor Value (BRG)
UART Baud Rate Error (%)
The baud rate error relative to the acceptable baud rate is calculated using the following
equation:
For reliable communication, the UART baud rate error must never exceed 5 percent.
Table 71 provides information about data rate errors for 5.5296 MHz System Clock.
