Signal Definitions
3.1
The SC2200 is highly configurable as illustrated in Figure
3-1 on page 25. Strap options and register programming
are used to set various modes of operation and specific
signals on specific balls. This section describes which sig-
nals are available on which balls and provides configuration
information:

where relevant, Pull-Up or Pull-Down resistors are indi-

necessary configuration for each signal is listed as well.

For each GPIO signal, there is an optional pull-up
resistor on the relevant ball. After system reset, the
pull-up is present.
This pull-up resistor can be disabled via registers in
the Core Logic module. The configuration is without
regard to the selected ball function (except for
GPIO12, GPIO13, and GPIO16). Alternate functions
for GPIO12, GPIO13, and GPIO16 control pull-up
resistors.
For more information, see Section 6.4.1 "Bridge,
GPIO, and LPC Registers - Function 0" on page 198.
Configuration settings listed in this table are with
regard to the Pin Multiplexing Register (PMR). See
Section 4.2 "Multiplexing, Interrupt Selection, and
Base Address Registers" on page 76 for a detailed
description of this register.

The # symbol in a signal name indicates
that the active or asserted state occurs
when the signal is at a low voltage level.
Otherwise, the signal is asserted when
at a high voltage level.
A / in a signal name indicates both func-
tions are always enabled (i.e., cycle mul-
tiplexed).
A + in signal name indicates the function
is available on the ball, but that either
strapping options or register program-
ming is required to select the desired
function.
