Debug Circuitry
The Am186CC microcontroller router reference design provides the following
debug circuitry.
TIP Interface
NOTE: See sheet 13 in the schematics for the TIP interface connector circuitry.
Several debug and configuration options make the Am186CC microcontroller
router reference design a useful tool for the development of specific applications.
The reference design offers an interface to the TIP debug board (available
separately from AMD) that provides status indicators and debug peripherals, debug
headers to provide access to most critical pins on the Am186CC microcontroller,
a reset configuration switch to define specific system parameters, and a pinstrap
configuration switch to define particular pin functions.
The TIP is a small debug board to aid in testing, debug, and software development
of system applications based on the Am186CC microcontroller. The TIP provides
the following features:
• An 8-bit on-board Flash memory that you can select as the default boot device
• A 2-line x 20-character LCD to provide status information
• Eight hexadecimal LED displays to use for status codes
• Eight readable and writable LEDs for status indication
• Two RS-232 DCE serial ports to enable direct connection to a PC
• A PC-compatible parallel port
• A secondary reset button for the Am186CC microcontroller router reference
design.
• A 10BaseT Ethernet port
