NAME AND DESCRIPTION
Receive Multiframe. Set on receive multiframe boundaries.
Transmit Multiframe. Set on transmit multiframe boundaries.
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 RFDLM1 or
RFDLM2.
Receive FDL Abort. Set when eight consecutive one’s are received in the FDL.
Receive Signaling Change. Set when the DS21352/552 detects a change of state in
any of the robbed–bit signaling bits.
