Module JTAG Interface Connector, P11
The Module's JTAG Interface Connector is a 14-pin female vertical header that is labeled P11 on
the development board. The connector mates with the JTAG connector on the embedded module.
The Module's JTAG Connector pins are tied to the debugger connector (see "JTAG Debugger
Connector, P12").
Since the modules' JTAG connectors are mounted on the bottom side of the modules, the pin 1
location is mirrored from that of the Development board's mating JTAG connector (P11). The
resulting pin mapping is indicated in the Module JTAG Interface Connector Pin Assignments table
below.
