2.3 Debug Support
The 56F8323EVM 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.
2.3.1 JTAG Connector
The JTAG connector on the 56F8323EVM allows the connection of an external Host Target
Interface for downloading programs and working with the 56F8323’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.
for this connector.
When this connector is used with an external Host Target Interface, the parallel JTAG interface
should be disabled by placing a jumper in jumper block JG3. Refer to
selection options.
