Standard EJTAG Timing
chosen providing 12 signals and 12 ground pins. This guarantees elimination of noise problems by incorporating signal-ground type arrangement.
Refer to the RC32334/RC32332 User Reference Manual for connector pinout and mechanical specifications.
Figure 4 represents the timing diagram for the EJTAG interface signals.
The standard JTAG connector is a 10-pin connector providing 5 signals and 5 ground pins. For Standard EJTAG, a 24-pin connector has been
