The UART function contains a programmable baud generator and a set of fixed dividers that divide the 48-MHz clock input down to the expected baud rate.
Figure 12-65 shows the baud rate generator and associated controls.
Figure 12-65 UART Baud Rate GenerationBefore initializing or modifying clock parameter controls (UART_DLH, UART_DLL), UART_MDR1[2-0] MODE_SELECT = DISABLE must be set to 0x7. Failure to observe this rule can result in unpredictable module behavior.
