COMP_ADDR—Compare Address
This 8-bit value is compared to incoming address bytes.
The UART Baud Rate High and Low Byte registers (Tables 69 and 70) combine to create
a 16-bit baud rate divisor value (BRG[15:0]) that sets the data transmission rate (baud
rate) of the UART.
The UART data rate is calculated using the following equation:
UART Baud Rate (bits/s)
For a given UART data rate, calculate the integer baud rate divisor value using the follow-
ing equation:
Table 69. UART Baud Rate High Byte Register (U0BRH)
Table 70. UART Baud Rate Low Byte Register (U0BRL)
Table 68. UART Address Compare Register (U0ADDR)
