Signal Descriptions
Table 4 on page 14 contains a description of the
Am186CC controller signals. Table 3 describes the
terms used in Table 4. The signals are organized
alphabetically within the following functional groups:
n Bus interface/general-purpose
n Clocks/reset/watchdog timer (page 17)
n No connects (page 18)
n Power and ground (page 19)
n Debug support (page 19)
n Chip selects (page 19)
n DRAM (page 20)
n Interrupts (page 21)
n Programmable I/O (PIOs) (page 22)
n Programmable timers (page 22)
n Asynchronous serial ports (UART and High-Speed
n Synchronous serial interface (SSI) (page 23)
n HDLC synchronous communications: channels
n Universal serial bus (USB) (page 26)
For pinstraps, refer to Table 31, “Reset Configuration
Pins (Pinstraps),” on page A-10.

Definition
Pin alternate function; a pin defaults to the
signal named without the brackets
Reset configuration pin (pinstrap)
Refers to the physical wire
An external or power-on reset is caused by
asserting RES. An internal reset is initiated by
the watchdog timer. A system reset is one that
resets the Am186CC controller (the CPU plus
the internal peripherals) as well as any external
peripherals connected to RESOUT. An external
reset always causes a system reset; an internal
reset can optionally cause a system reset.
Refers to the electrical signal that flows across
a pin
A line over a signal name indicates that the
signal is active Low; a signal name without a
line is active High.
