err_ts_frm Output
tsclk
Indicates the frame was malformed. Possible causes
are:
■ Calendar did not begin with a framing word.
■ Hitless bandwidth repositioning is turned on, and
calendar select word was not ‘b01 or ‘b10.
■ Unexpected framing word was in the calendar
portion of the frame.
Asserted synchronous to stat_ts_dip2state.
err_ts_dip2 Output
Indicates the calculated DIP-2 did not match the DIP-
2 word in the status frame. Asserted synchronous to
stat_ts_dip2state
.
ctl_ts_callen[7:0] Input
Sets the expected length of the calendar in the status
frame. This port is absent if Asymmetric Port
Support is turned on. Only change at reset, or when
ctl_ts_rsfrm
and stat_ts_disabled are both
asserted.
ctl_ts_calm[7:0] Input
Sets the expected number of status calendar
repetitions between framing and DIP-2 in the status
frame. This port is absent if Asymmetric Port
Support is turned on. Only change at reset, or when
ctl_ts_rsfrm
and stat_ts_disabled are both
asserted.
stat_ts_calsel Output
Indicates the currently selected calendar when
Hitless B/W reprovisioning is turned on. Zero
indicates ‘b01, and one indicates ‘b10. It is set to
zero when Hitless B/W reprovisioning is turned off.
This port is absent if Asymmetric Port Support is
turned off.
tav_clk Input
tav_clk
Avalon-MM clock. Signals prefixed by tav_ are
synchronous to this clock. This port is absent if
Asymmetric Port Support is turned off.
tav_address[3:0] Input
Avalon-MM address. This port is absent if
Asymmetric Port Support is turned off.
tav_chipselect Input
Avalon-MM chip select. This port is absent if
Asymmetric Port Support is turned off.
tav_write Input
tav_clk
Avalon-MM write enable. This port is absent if
Asymmetric Port Support is turned off.
tav_read Input
Avalon-MM read enable. This port is absent if
Asymmetric Port Support is turned off.
tav_writedata[15:0] Input
Avalon-MM write data. This port is absent if
Asymmetric Port Support is turned off.
tav_readdata[15:0] Output
Avalon-MM read data. This port is absent if
Asymmetric Port Support is turned off.
tav_waitrequest Output
Avalon-MM wait request. This port is absent if
Asymmetric Port Support is turned off.
