Electrical Parameters
4.6.6 JTAG Interface Timing
The following parameters are applicable for communication through the JTAG debug
interface. The JTAG module is fully compliant with IEEE1149.1-2000.
Note: These parameters are not subject to production test but verified by design and/or
characterization.

1) The falling edge on TCK is used to generate the TDO timing.
2) The setup time for TDO is given implicitly by the TCK cycle time.
