2.8 Debug Support

The 56852EVM 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.
