■ UART1: 0x4000.D000
■ UART2: 0x4000.E000
Note that the UART module clock must be enabled before the registers can be programmed (see
page 264). There must be a delay of 3 system clocks after the UART module clock is enabled before
any UART module registers are accessed.
Note: The UART must be disabled (see the UARTEN bit in the UARTCTL register on page 730)
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.
