Electrical Specifications
6.3.15 JTAG Signals
The TDI and TDO JTAG signals use a “Q5” buffer type
while the TMS signal uses a “Q7”. For a detailed explana-
tion of buffer types, see Table 2-4 "Buffer Type Character-
istics" on page 28.
In this subsection, unless otherwise noted:
• All timing specifications are specified under the oper-
Note 1. t
Note 2. Signal is referenced to TCK high-to-low edge.
