• Set the PRYE bit in the UiMR register to "0"(parity disabled)
• Set the STPS bit in the UiMR register to "0" (1 stop bit)
• Set the CRD bit in the UiC0 register to "0" (CTSi/RTSi enabled), the CRS bit to "1" (RTSi selected)

In UART mode, the frequency set by the UiBRG register (i=0 to 2) divided by 16 become the bit rates.
Table 14.9 lists example of bit rate and settings.
