A.10.3 Interrupt Controller Use Guidelines
All interrupts in
that are shaded in orange must be kept masked (reset default state). (See the
Interrupt Controller Functional Description section in the Interrupt Controller chapter of the OMAP36xx
TRM.)
A.11 System Control Module
NOTE:
This subsection provides a quick reference about the device pads, that are not connected to
any pin. Cells highlighted in orange in the tables indicate pads with removed functionality in
the OMAP36xx in CYN package devices. These pads are still present on the die; therefore,
their configuration settings are provided to control their activity and for debug purposes.
A.11.1 SCM Environment
sys_boot4 is no longer used for boot mode selection (see
).
