RI
Receive Interrupt Flag.
Set to 1 by hardware when a byte of data has been received by UART0 (set at the STOP
bit sampling time). When the UART0 interrupt is enabled, setting this bit to 1 causes the
CPU to vector to the UART0 interrupt service routine. This bit must be cleared manually
by firmware.
