The USART contains features allowing management of the Modem Signals DTR, DSR, DCD and RI. In the SAM9260,
only the USART0 implements these signals, named DTR0, DSR0, DCD0 and RI0.
only the USART0 implements these signals, named DTR0, DSR0, DCD0 and RI0.
The USART1 and USART2 do not implement all the modem signals. Only RTS and CTS (RTS1 and CTS1, RTS2 and
CTS2, respectively) are implemented in these USARTs for other features.
