Re: Writing an ISR in pure assembly

See https://github.com/pabigot/freertos-mspgcc for FreeRTOS using MSPGCC as
of mid 2012.  The use of naked is in Source/portable/GCC/MSP430, but does
not apply to the timer ISR itself.  It was not necessary to use external
assembly sources.

http://pabigot.github.io/bsp430/freertos_8h.html may also be useful.

As I recall I did have FreeRTOS working under BSP430 and so supporting all
MCUs in the product line.  The freertos-bsp430 repository was intended to
supersede freertos-mspgcc; at this point there is no public difference,
though I seem to have some pending updates in my local workspace.  None of
that is actively supported but it could be if people find it useful.

Rapidly troubleshoot problems before they affect your business. Most IT 
organizations don't have a clear picture of how application performance 
affects their revenue. With AppDynamics, you get 100% visibility into your
