z
Bits 3:2 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to 
zero when this register is written. These bits will always return zero when read.
z
Bits 1:0 – RXRDYx [x=1..0]: Receive Ready x
This flag is cleared by reading from DATAx register or writing a one to it.
This flag is set when a Sequencer x has received a new data word, and will generate an interrupt request if INTEN-
CLR/SET.RXRDYx is set to one.
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the Receive Ready x interrupt flag.
