  • State 010: A CRC24 error was detected and timer1 is counting
  • State 011: Waiting for a Discontinuity while timer2 is counting
  • State 100: Waiting to re-establish the implied burst sub-sequence
  • State 101: Waiting for the expected sequence
  • State 110: Fatal Error, waiting for assertion of CTL_RX_RETRANS_RESET
