3.6 Miscellaneous Connectors
The C6416 DSK has 3 additional connectors to aid the user in developing with this
product. They are described in the following sections.
3.6.1 J201, USB Connector
Connector J201 provides a Universal Serial Bus (USB) Interface to the embedded
JTAG emulation logic on the DSK. This allows for code development and debug
without the use of an external emulator. The signals on this connector are shown in the
below.
3.6.2 J8, External JTAG Connector
The TMS320C6416 DSK is supplied with a 14 pin header interface, J8. This is the
standard interface used by JTAG emulators to interface to Texas Instruments DSPs.
The pinout for the connector is shown figure 3-6 below.
