One Second Timer.
Set on increments of one second based on RCLK;
will be set in increments of 999 ms, 999 ms, and 1002 ms every 3
seconds.
Receive FDL Buffer Full.
Set when the receive FDL buffer (RFDL)
fills to capacity (8 bits).
Transmit FDL Buffer Empty.
Set when the transmit FDL buffer
(TFDL) empties.
Receive FDL Match Occurrence.
Set when the RFDL matches
either RMTCH1 or RMTCH2.
Receive FDL Abort.
Set when eight consecutive one’s are received
in the FDL.
Receive Signaling Change.
Set when the DS21Q42 detects a change
of state in any of the robbed–bit signaling bits.
