Debug Leds; Debug Support; Schematic Diagram Of The Debug Led Interface - Motorola DSP56F826EVM Hardware User Manual

2.7 Debug LEDs

Six on-board Light-Emitting Diodes (LEDs) are provided to allow real-time debugging for
user programs. These LEDs will allow the programmer to monitor program execution
without having to stop the program during debugging; refer to
controlled by Port B's PB0 signal. User LED2 is controlled by PB1. User LED3 is
controlled by PB2. User LED4 is controlled by PB3. User LED5 is controlled by PB4.
User LED6 is controlled by PB5. Setting PB0, PB1, PB2, PB3, PB4 or PB5 to a Logic
One value will turn on the associated LED.

2.8 Debug Support

The 56F826EVM provides an on-board Parallel JTAG Host Target Interface and a JTAG
interface connector for external 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.
