The first thing to consider when programming the UART is the baud-rate divisor (BRD), since the
UARTIBRD and UARTFBRD registers must be written before the UARTLCRH register. Using the
equation described in “Baud-Rate Generation” on page 267, the BRD can be calculated:
BRD = 20,000,000 / (16 * 115,200) = 10.8507
which means that the DIVINT field of the UARTIBRD register (see page 280) should be set to 10.
The value to be loaded into the UARTFBRD register (see page 281) is calculated by the equation:
UARTFBRD[DIVFRAC] = integer(0.8507 * 64 + 0.5) = 54
With the BRD values in hand, the UART configuration is written to the module in the following order:
1.
2.
3.
4.
5.
Register Map
Table 12-1 on page 271 lists the UART registers. The offset listed is a hexadecimal increment to the
register’s address, relative to that UART’s base address:

UART0: 0x4000.C000
UART1: 0x4000.D000
UART2: 0x4000.E000
Disable the UART by clearing the UARTEN bit in the UARTCTL register.
Write the integer portion of the BRD to the UARTIBRD register.
Write the fractional portion of the BRD to the UARTFBRD register.
Write the desired serial parameters to the UARTLCRH register (in this case, a value of
0x0000.0060).
Enable the UART by setting the UARTEN bit in the UARTCTL register.
The UART must be disabled (see the UARTEN bit in the UARTCTL register on page 284)
before any of the control registers are reprogrammed. When the UART is disabled during
a TX or RX operation, the current transaction is completed prior to the UART stopping.
