2.3.1  P1, JTAG Interface

The eZdsp

TM

 F2808 is supplied with a 14-pin header interface, P1. This is the

standard interface used by JTAG emulators to interface to Texas Instruments DSPs.

The positions of the 14 pins on the P1 connector are shown in the diagram below as
viewed from the top of the eZdsp.

The definition of P1, which has the JTAG signals is shown below.
