3.4 Chip Specific Implementation Signal Issues
3.4.1 RSTOUT Signal Functions
MMC2114 • MMC2113 • MMC2112 — Rev. 1.0
MOTOROLA
CAUTION:
Most modules are designed to allow expanded capabilities if all the
module signals to the pads are implemented. This subsection discusses
how these modules are implemented on the MMC2114, MMC2113, and
MMC2112.
The RSTOUT signal has these multiple functions:
External logic used to drive reset configuration data during reset needs
to be considered when using the RSTOUT signal for a function other
than an indication of reset.

For More Information On This Product,
Whenever the internal system reset is asserted, the RSTOUT
signal will always be asserted to indicate the reset condition to the
system.
If the internal reset is not asserted, then setting the FRCRSTOUT
bit in the Reset Control Register (RCR) will assert the RSTOUT
signal for as long as the FRCRSTOUT bit is set. See
Control
If the internal reset is not asserted and the FRCRSTOUT bit is not
set, then setting the SHOWINT bit in the Chip Configuration
Register will reflect internal interrupt requests out to the RSTOUT
signal.
If the internal reset is not asserted and the FRCRSTOUT bit is not
set and the SHOWINT bit is not set, then the RSTOUT signal will
be negated to indicate to the system that there is no reset
condition.
