System Features and Components
The Am186CC microcontroller router reference design is a single-sided,
6.5 x 9.75-inch, printed circuit board that integrates the Am186CC microcontroller
and I/O interfaces onto one board, enabling you to develop ISDN, Ethernet, High-
Speed UART, USB, and POTS applications.
The following sections explain the operation of the board in detail:
