17.1 New Features in Stellaris Boot Loader
17.1.1 Added Internal Pull up/down to boot loader. (Reference 10876)
The boot loader has the ability to check an external pin to see if it is set to a high or low voltage level
and remain in the boot loader. However, the boot loader did not have a way to enable an internal
pull-up or pull-down when using this feature. Two additional configuration options were added to
enable an internal pull-up resistor by defining FORCED_UPDATE_WPU or an internal pull-down by
defining FORCED_UPDATE_WPD value. These values are mutually exclusive and only one or the
other should be used when using an internal pull resistor. If an external resistor pull-up or pull-down
is used then neither valued should be defined.
17.2 New Features in Stellaris Peripheral Driver Library
17.2.1 Added IntPendSet() and IntPendClear() APIs (Reference 10694)
The IntPendSet() and IntPendClear() APIs have been added to the interrupt controller driver. They
allow an interrupt to be pended (made to appear as if it has occurred) or unpended (made to
appear as if it has not occurred). Unpending an interrupt is sometimes useful pr ior to enabling it
(if the process of configuring the interrupt source causes a false trigger prior to the interrupt being
enabled).
