(1) When the UFORM bit in the UiC0 register (i = 5, 6) is set to 0 (LSB first)
(2) When the UFORM bit is set to 1 (MSB first)

The above applies under the following conditions:
ST: Start bit
P: Parity bit
SP: Stop bit
In UART mode, the baud rate is the clock frequency divided by the setting value of the UiBRG register
(i = 5 and 6) and again divided by 16. Table 17.26 lists an example of baud rate setting.
As shown in Figure 17.54, the UFORM bit in the UiC0 register (i = 5 and 6) determines a bit order. This
function is can be used when data length is 8 bits long.
