Designing Your Target System’s Emulator Connector (14-Pin Header)

C-2

C.1 Designing Your Target System’s Emulator Connector (14-Pin Header)

JTAG target devices support emulation through a dedicated emulation port.

This port is accessed directly by the emulator and provides emulation func-

tions that are a superset of those specified by IEEE 1149.1. To communicate

with the emulator,

your target system must have a 14-pin header (two rows of

seven pins) with the connections that are shown in Figure C–1. Table C–1

describes the emulation signals.

Although you can use other headers, the recommended unshrouded, straight

header has these DuPont connector systems part numbers:

- 65610–114

- 65611–114

- 67996–114

- 67997–114

schematics and wiring diagrams in this appendix.
