Transmit Interrupt Status. This bit is set to 1 if the
UARTTXINTR transmit interrupt is asserted, which occurs
when the transmit FIFO is not full. It is set to 0 when the
transmit FIFO is full.
Receive Interrupt Status. This bit is set to 1 if the
UARTRXINTR receive interrupt is asserted, which occurs
when the receive FIFO is not empty. It is set to 0 when the
receive FIFIO is empty.
Modem Interrupt Status. This bit is set to 1 if the
UARTMSINTR modem status interrupt is asserted. This
bit is cleared by writing any value to this register.
Reserved. Unknown During Read.
