Software flow control between two devices is accomplished by using interrupts to indicate the status of the UART. Interrupts can be generated for the U1CTS signal using bit 3 of the UART:IMSC register. The raw and masked interrupt status can be checked using the UART:RIS and UART:MIS registers. These interrupts can be cleared using the UART:ICR register.
