The pins used for interfacing the USART may be multiplexed with the PIO lines. The program-
mer must first program the PIO controller to assign the desired USART pins to their peripheral
function. If I/O lines of the USART are not used by the application, they can be used for other
purposes by the PIO Controller.
All the pins of the modems may or may not be implemented on the USART within a product. Fre-
quently, only the USART1 is fully equipped with all the modem signals. For the other USARTs of
the product not equipped with the corresponding pin, the associated control bits and statuses
have no effect on the behavior of the USART.
