U1TXI—UART 1 Transmitter Interrupt Request
0 = No interrupt request is pending for the UART 1 transmitter.
1 = An interrupt request from the UART 1 transmitter is awaiting service.
PCxI—Port C Pin x Interrupt Request
0 = No interrupt request is pending for GPIO Port C pin x.
1 = An interrupt request from GPIO Port C pin x is awaiting service.
Where x indicates the specific GPIO Port C pin number (0–3).
