SYMBOL
POSITION NAME AND DESCRIPTION
TAF
SR2.3
Transmit Align Frame. Set every 250 ns at the beginning of align
frames. Used to alert the host that the TAF and TNAF registers need to
be updated.
LOTC
SR2.2
Loss of Transmit Clock. Set when the TCLK pin has not transitioned
for one channel time (or 3.9 ns). Will force the LOTC pin high if enabled
via TCR2.0.
RCMF
SR2.1
Receive CRC4 Multiframe. Set on CRC4 multiframe boundaries; will
continue to be set every 2 ms on an arbitrary boundary if CRC4 is
disabled.
TSLIP
SR2.0
Transmit Elastic Store Slip. Set when the elastic store has either
repeated or deleted a frame of data.
