2.6 Debug LEDs
Three 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
. User
LED1 is controlled by Port B’s PB0 signal. User LED2 is controlled by PB1. User LED3
is controlled by PB2. Setting PB0, PB1 or PB2 to a Logic One value will turn on the
associated LED.

2.7 Debug Support
The 56F805EVM 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.
