231 / 410 page  Page 217 TMP89FS60 RA001 16.8 Transfer Baud Rate The transfer baud rate of UART is set by UART0CR1<BRG>, UART0DR and UART0CR2<RTSEL>. Table 16-6 and Table 16-7 show the settings of UART0DR and UART0CR2<RTSEL> for general baud rates and operating fre- quencies. For independent calculation of transfer baud rates, refer to "16.8.1 Transfer baud rate calculation method".
