LOTC
SR2.2
Loss of Transmit Clock. Set when the TCLK pin has not
transitioned for one channel time (or 3.9 s).
Receive CRC4 Multiframe. Set on CRC4 multiframe
boundaries; will continue to be set every 2 ms on an arbitrary
boundary if CRC4 is disabled.
Transmit Elastic Store Slip. Set when the elastic store has
either repeated or deleted a frame of data.
