Emulator Connection Without Signal Buffering for the MCU

Figure 5-9 shows the connection between the MCU and JTAG header for a single-processor configuration.

If the distance between the JTAG header and the MCU is greater than 6 inches, the emulation signals

must be buffered. If the distance is less than 6 inches, buffering is typically not needed. Figure 5-9 shows

the simpler, no-buffering situation. For the pullup and pulldown resistor values, see Section 2.4, Signal

Descriptions.

See Figure 5-48 for JTAG/GPIO multiplexing.

NOTE

The 2806x devices do not have EMU0/EMU1 pins. For designs that have a JTAG Header

on-board, the EMU0/EMU1 pins on the header must be tied to VDDIO through a 4.7-kΩ

(typical) resistor.
