Bits 13,12 – TXURx Transmit Underrun x [x=1..0]
This flag is cleared by writing a '1' to it.
This flag is set when a Transmit Underrun condition occurs in Sequencer x, and will generate an interrupt
request if INTENCLR/SET.TXURx is set to '1'.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit will clear the Transmit Underrun x interrupt flag.
Bits 9,8 – TXRDYx Transmit Ready x [x=1..0]
This flag is cleared by writing to DATAx register or writing a '1' to it.
This flag is set when Sequencer x is ready to accept a new data word to be transmitted, and will generate
an interrupt request if INTENCLR/SET.TXRDYx is set to '1'.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit will clear the Transmit Ready x interrupt flag.
Bits 4,5 – RXORx Receive Overrun x [x=1..0]
This flag is cleared by writing a '1' to it.
This flag is set when a Receive Overrun condition occurs in Sequencer x, and will generate an interrupt
request if INTENCLR/SET.RXORx is set to '1'.
Writing a '0' to this bit has no effect.
Writing a '1' to this bit will clear the Receive Overrun x interrupt flag.
Bits 1,0 – RXRDYx Receive Ready x [x=1..0]
This flag is cleared by reading from DATAx register or writing a '1' to it.
This flag is set when a Sequencer x has received a new data word, and will generate an interrupt request
if INTENCLR/SET.RXRDYx is set to '1'.
Writing a '0' to this bit has no effect.
