Note 1:
Delay (latency) from a particular master port signal to the corresponding slave port signal.
Note 2:
Skew values are with respect to a signal from the arbitrated master to the same signal on the selected secondary slave port.
Note 3:
Skew from any set of two signals at a master port to the corresponding two signals at the selected slave port.
Note 4:
Delay path from a selected slave port STDO to the arbitrated master’s TDO.
Note 5:
Half-cycle path from falling edge STCK/STDO (launch) to rising edge TCK/TDO (capture), pass-through path (see Figure 11-2).
Note 6:
TCK corresponds to each master port clock when being used to configure the core JTAG controller, e.g., ETCK or TCK1 or TCK2.
TDI, TMS correspond to the master port TDI, TMS, e.g., ETDI, ETMS or TDI1, TMS1 or TDI2, TMS2. TDO corresponds to the
master port TDO when being used to configure the core JTAG controller, e.g., ETDO or TDO1 or TDO2.
Note 7:
STCK corresponds to each slave port clock, e.g., STCK1–STCK18. STDI, STMS correspond to the slave port TDI, TMS, e.g.,
STDI1–STDI18, STMS1–STMS18. STDO corresponds to the slave port STDO1–STDO18.
