The USART pins may be multiplexed with the I/O Controller lines. The user must first configure
the I/O Controller to assign these pins to their peripheral functions. Unused I/O lines may be
used for other purposes.
To prevent the TXD line from falling when the USART is disabled, the use of an internal pull up
is required. If the hardware handshaking feature or modem mode is used, the internal pull up on
TXD must also be enabled.
The clock for the USART bus interface (CLK_USART) is generated by the Power Manager. This
clock is enabled at reset, and can be disabled in the Power Manager. It is recommended to dis-
able the USART before disabling the clock, to avoid freezing the USART in an undefined state.
The USART interrupt request line is connected to the interrupt controller. Using the USART
interrupt requires the interrupt controller to be programmed first.
