2.7.1 JTAG Connector
The JTAG connector on the 56F8367EVM allows the connection of an external host target
interface for downloading programs and working with the 56F8367’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.
