2.6 Debug LED
An on-board Light-Emitting Diode, (LED), is provided to allow real-time debugging for user
programs. This LED allows the programmer to monitor program execution without having to
stop the program during debugging; refer to
Figure 2-4
. LED8 is controlled by the MOSI signal
line. Setting MOSI to a Logic One value will turn on the LED.

2.7 Debug Support
The 56F803EVM provides an on-board Parallel JTAG Host Target Interface and a JTAG
interface connector for external Host Target Interface support. Two interface connectors are
provided to support each of these debugging approaches. These two connectors are designated
the JTAG connector and the Host Parallel Interface Connector.
2.7.1 JTAG Connector
The JTAG connector on the 56F803EVM allows the connection of an external Host Target
Interface for downloading programs and working with the 56F803’s registers. This connector is
used to communicate with an external Host Target Interface which passes information and data
back and forth with a host processor running a debugger program.
Table 2-3
shows the pin-out
for this connector.
