TABLE 6: UART CHANNEL [1:0] INTERRUPT CLEARING:
RXRDY is cleared by reading data in the RX FIFO until it falls below the trigger level.
RXRDY Time-out is cleared by reading data until the RX FIFO is empty.
RX Line Status interrupt clears after reading the LSR register.
TXRDY interrupt clears after reading ISR register that is in the UART channel register set.
Modem Status Register interrupt clears after reading MSR register that is in the UART channel register set.
RTS/CTS or DTR/DSR delta interrupt clears after reading MSR register that is in the UART channel register set.
Xoff/Xon interrupt clears after reading the ISR register that is in the UART channel register set.
Special character detect interrupt is cleared by a read to ISR or after the next character is received.
TIMER Time-out interrupt clears after reading the TIMERCNTL register that is in the Device Configuration register set.
MPIO interrupt clears after reading the MPIOLVL register that is in the Device Configuration register set.
