3.8 Spectrum Spreader
TCP/IP Development Boards that carry the CE mark have a Rabbit 2000 microprocessor
that features a spectrum spreader, which helps to mitigate EMI problems. By default, the
spectrum spreader is on automatically for TCP/IP Development Boards that carry the CE
mark when used with Dynamic C 7.32 or later versions, but the spectrum spreader may
also be turned off or set to a stronger setting. The means for doing so is through a simple
change to the following BIOS line in a way that is similar to the clock doubler described
above.
There is no spectrum spreader functionality for TCP/IP Development Boards that do not
carry the CE mark or when using any TCP/IP Development Kit with a version of Dynamic
C prior to 7.30.

#define ENABLE_SPREADER 1
NOTE: The strong spectrum-spreading setting is unnecessary for the TCP/IP Develop-
ment Board.
// Set to 0 to disable spectrum spreader
// 1 to enable normal spreading, or
// 2 to enable strong spreading.
