Data Ready RX FIFO interrupt
Asserted when new data arrives RX FIFO
Write 1 to clear bit.
Data Sent TX FIFO interrupt
Asserted when packet transmitted on TX. If
AUTO_ACK is activated, this bit is set high
only when ACK is received.
Write 1 to clear bit.
Maximum number of TX retransmits

Write 1 to clear bit. If MAX_RT is asserted
it must be cleared to enable further
communication.
