Clock Domain
Controls the edge of tsclk on which tstat is
sampled (1= positive edge; 0= negative edge). Only
change at reset.
Number of status frames which must be error free
(err_ts_frm=0 and err_ts_dip2=0) to assert
stat_ts_sync. Zero is interpreted as one. Only
change at reset.
Number of status frames which must be errored
(err_ts_frm=1 and err_ts_dip2=1) to deassert
stat_ts_sync. Zero is interpreted as one. Only
change at reset.
Indicates status frames are well formed, according to
hysteresis with ctl_ts_synch_good_threshold
and ctl_ts_bad_threshold.
Forces the status state machine into the disabled
state, beginning at the next frame, at which time
stat_ts_sync is forced low and
stat_ts_disabled is asserted.
Indicates that the status state machine is in the
disabled state. Asserted at startup, after the negative
edge of stat_ts_sync, or at a frame boundary if
ctl_ts_rsfrm is asserted. Deasserted when a
potentially valid framing pattern is detected. A
potentially valid framing word is ‘b11 followed by
anything other than ‘b11.
Indicates that the status state machine is in DIP-2
state.
Indicates that the status state machine is in framing
state.
Port number for the received status value.
Received status value.
