Standard JTAG Timing
Figure 8 represents the timing diagram for the EJTAG interface signals.
*Notice: The information in this document is subject to change without notice
The standard JTAG connector is a 10-pin connector providing 5 signal and 5 ground pins. For Enhanced JTAG, a 24-pin connector has been
chosen providing 12 signal pins and 12 ground pins. This guarantees the elimination of noise problems by incorporating a signal-ground type arrange-
ment.
